The Murky Hollow includes encounters of EL 5-7, but is suitable for use with any D&D campaign.
Locals take care to avoid this marshy valley at night, when strange vapors and weird apparitions rise from the very ground to befuddle the unwary visitor, or even choke off life. By day the valley seems unnaturally green and silent, as though something terrible has gone to ground in the surrounding wood and lies, brooding, until it can go forth again at dusk. What power lurks in the murky hollow?
Background for the DM
The murky hollow is a shallow valley that sometimes floods during heavy rains. Throughout much of the year, a narrow stream flows through the bottom, but the stream dries up in late summer and in winter. A series of mineral springs and small geysers, however, keep any number of small pools and bogs full of water year round. When the stream flows, all these small bodies of water are connected.
The vapors the locals fear are usually nothing more than normal fog coming from a few of the hot springs (and the occasional geyser eruption). During the day, the springs and geysers merely make the place seem cloyingly humid, but at night the air temperature drops, giving rise to banks of shadowy fog.
Tales of weird apparitions and inexplicable deaths in the hollow have a basis in fact. Rotting vegetation lying in the streambed gives off marsh gases that sometimes spontaneously ignite, thus creating natural will-o'-wisps. A few of the geysers vent massive clouds of carbon dioxide (and traces of other gases) from time to time as well. This gas is beneficial to the plant life in the hollow, but people and animals caught in an eruption can literally drown before they're aware of the danger.
Choking Gas Cloud Trap: CR 5; gas; timed trigger; no reset; gas cloud 15 feet high; Search DC --; Disable Device DC --; Cost:--.
An eruption releases a cloud of gas 15 feet high and 3d4x10 feet in diameter. The cloud drifts on the wind for 1d4 hours before finally settling in some low area (the gas is heavier than air). The gas isn't normally visible, but it contains some water vapor and might form a light fog (partial concealment, 10% miss chance) at night or in cold weather. The gas is mostly odorless, but it might have a slight hint of sulfur smell. Gas eruptions can occur any time of the day or night.
Characters most often encounter the gas by walking into a stagnant cloud of the stuff, but they may encounter a cloud on the move (a cloud typically moves at a speed of 10-30 feet a round in the direction the wind blows). In the worst case, a cloud could settle over the party and then stay in place.
Upon first encountering the cloud, characters can make a DC 25 Survival check to notice telltale signs of the cloud (heavy air, a hint of rotten egg smell, animals in distress) or a DC 30 Spot check to notice visible signs of the cloud's presence (usually dead or dying animals). A successful Survival check reveals the cloud's basic nature. A successful Spot check reveals some clue, but provides no real information about the cloud, but a DC 20 Knowledge (nature or geography) check reveals the existence of such clouds.
Creatures in a cloud can speak, and they seem to breathe normally, at least as first. In fact, once inside the cloud a character effectively begins holding her breath because there's no oxygen in the cloud. After 1d4 rounds of involuntarily holding her breath, a character can make a DC 15 Wisdom or Survival check to notice the problem. If this check fails, the character noticed nothing unusual until she must make her first Constitution check to keep holding her breath (see page 304 in the Dungeon Master's Guide), or until someone else mentions the problem. In addition, the gas snuffs out any nonmagical flames the party carries. Torches, lanterns, or candles flicker immediately and go out 1 full round later.
The gas isn't toxic, and surviving an encounter with a cloud merely requires getting out before passing out. A character can do this by moving to the edge of the cloud or getting more than 15 feet above the ground. A character could accomplish the latter by finding a hill to scale or climbing a tree.
After becoming aware of the hazard the gas clouds pose, a character can make a DC 15 Survival check to avoid further contact with them. Doing so entails avoiding low ground and staying aware of the prevailing wind. Movement on the local or overland scale (see Chapter 9 in the Player's Handbook) is reduced to one half while avoiding gas clouds.
In addition to the natural hazards, the hollow could be home to any number of mischievous or hostile creatures, as noted in the next section.
A narrow country road crosses the hollow, so the characters could pass through it on their way somewhere else. The road connects two villages, and local people pass through the hollow fairly often, but usually only during daylight. The characters also might be drawn there in response to any number of rumors or tall tales, as noted below:
A Visit to the Hollow
The hollow could exist almost anywhere, but the following text assumes a hilly or mountainous area.
The track continues through the wooded hollow and out the other side for a distance of perhaps a mile and half. The stream mentioned earlier (if it's flowing at all) lies roughly in the center of the wood, and it must be crossed via a ford. The track proves reasonably firm and dry, though still both rocky and rutted at the same time, but the ground on either side is positively soggy.
In addition to occasional gas eruptions (see the previous section), PCs could encounter any of the following in the hollow.
Get Out of My Wood! (EL 7)
The treant Diobemun has dwelt in the hollow for at least a decade, drawn in part by the lush plant growth that the gas eruptions engender.
Diobemun, Treant: hp 66; see page 244 in the Monster Manual, except alignment neutral.
Tactics: Diobemun has developed a deep loathing for nonplant life, and for humanoids in particular. She doesn't even care for other treants, or for other plant creatures. Diobemun considers most treants foolishly sentimental and far too prone to forgive destructive activities by humanoids, and she thinks most other plant creatures are brainless louts.
Diobemun spends most of her time in the depths of the wood, where she tends a vast number of saplings she has grown from seed. Her charges might include blackwood trees or other varieties once thought extinct. If so, she probably found the seeds preserved in one of the hollow's bogs and coaxed them to grow.
Characters are most likely to meet Diobemun when they're attempting to avoid gas clouds, since doing so involves innumerable detours. The treant sometimes also hides near the track passing through the hollow just so that she can keep an eye on humanoids passing through the area.
Diobemun knows she can't just attack everyone she meets, but she's not above steering gullible newcomers toward areas filled with quicksand (see page 88 in the Dungeon Master's Guide), particularly if they inquire about lost treasure or wrecked wagons. She seethes with rage if she suspects visitors of mistreating the forest in any way.
Read or paraphrase the following aloud if the characters encounter Diobemun while they are not abusing the forest.
If the characters challenge the voice, Diobemun shakes her branches and greets them.
If the PCs tell Diobemun that they seek treasure, she tries not to express her disgust as she directs them to the nearest deadly danger.
In battle, Diobemun prefers to ambush her foes by hiding in a likely spot and pretending to be a tree (treat as a normal Hide check, with the usual +16 for a treant hiding in a forest). She begins by animating two trees on opposite sides of the enemy, and then she uses her trample attack against anyone who doesn't attempt melee combat with the trees. She assumes that such foes are spellcasters.
A Parade of Ghosts (EL 5-7)
Groups of forest gnomes occasionally search the hollow for rare wood and herbs. They also extract salts and trace minerals from the geysers and hot springs. They keep to themselves for the most part, and they move quietly through the trees on moonlit nights, when there's less chance that they'll be spotted or disturbed. Their trips have given rise to many tales of ghosts in the hollow.

The typical domestic animal has a starting attitude of indifferent, while wild animals are usually unfriendly. The forest gnome guide and the animal must study each other for 1 minute. This ability can also be used to influence a magical beast with an Intelligence score of 1 or 2, but the forest gnome guide takes a -4 penalty on the check.

Spell-Like Abilities: 1/day -- dancing lights, ghost sound (DC 12), prestidigitation, speak with animals (burrowing mammal only, duration 1 minute). Caster level 1st.
Bardic Knowledge: The forest gnome leader may make a bardic knowledge check with a bonus of +5 to see whether he knows some relevant information about local notable people, legendary items, or noteworthy places.
Bardic Music: The forest gnome leader can use his song or poetics to produce magical effects on those around him.
Countersong (Su): The forest gnome leader can counter magical effects that depend on sound by making a Perform check for each round of countersong. Any creature within 30 feet of him that is affected by a sonic or language-dependent magical attack can use the bard's Perform check result in place of his or her saving throw if desired. Countersong lasts for 10 rounds.
Fascinate (Sp): The bard can cause a single creature within 90 feet that can see and hear him to become fascinated with him. The bard's Perform check result is the DC for the opponent's Will save. Any obvious threat breaks the effect. Fascination lasts 5 rounds.
Inspire Competence (Su): The bard can use his music or poetics to aid an ally with a task. The ally must be within 30 feet and able to see and hear him, and he must be able to see the ally. The ally gets a +2 competence bonus on skill checks with a particular skill as long as he or she can hear the bard's music. The effect lasts as long as the bard concentrates, up to a maximum of 2 minutes. The bard can't inspire competence in himself. Inspire competence is a mind-affecting ability.
Inspire Courage (Su): Any ally who can hear the bard receives a +1 morale bonus on saves against charm and fear effects and a +1 morale bonus on attack and weapon damage rolls. The effect lasts for 5 rounds after the ally can no longer hear him.
Forest Gnome Traits: The forest gnome leader has a +2 racial bonus on saving throws against illusions, a +4 dodge bonus against giants, and a +1 racial bonus on attack rolls against kobolds, goblinoids, orcs, and reptilian humanoids. He also has a +4 racial bonus on Hide checks, which improves to +8 in a wooded area (already figured into the statistics given above). In addition, a forest gnome leader has the innate ability to use pass without trace as the spell (caster level 3rd).
Bard Spells Known (3/2; 0% chance of arcane spell failure): 0 -- daze (DC 12), detect magic, light, mage hand, message, prestidigitation; 1st -- cure light wounds, lesser confusion (DC 13), magic weapon.
Possessions: Masterwork studded leather, masterwork longsword, masterwork composite shortbow (+0 Str bonus), cloak of resistance +1,wand of cure light wounds (23 charges), scroll of animate rope, scroll of disguise self, scroll of endure elements, scroll of glitterdust, scroll of remove fear.
Tactics: The gnomes prefer to stick to business, but they keep a sharp lookout for Diobemun, and that makes them a little bit jumpy. Their first reaction upon meeting the PCs is to scatter, and after that they try to hide. Read or paraphrase the following when the gnomes first hear or spot the PCs.
If the PCs pursue, the bard tries to negotiate.
The gnomes are really just trying to get rid of the PCs by directing them toward the treant. No blackwood trees are in that area, but if the PCs obey the gnomes or ask Diobenum about blackwood trees, she flies into a rage and attacks.
The gnomes really don't want to fight, but if pressed, they try to keep their distance as long as possible by fleeing through the woods and firing their arrows. The bard uses grease spells and his scroll of glitterdust to slow down the party.
Not Just a Babbling Brook (EL 5-7)
A small group of allips infests the hollow. If you've decided that the rumor about the treasure caravan is true, the allips arose from the caravan drivers who foolishly lost their lives trying to save their cargoes. Otherwise, they're the spirits of equally foolish locals who spent too much time in the hollow and died in gas eruptions.
Allips (2-4): hp 26 each; see Monster Manual, page 10.
Tactics: The allips prefer to lurk in the trees, just within the 60-foot range of their babble ability. They babble for a round or two, then move in to make touch attacks. The allips are drawn to gas clouds, and they might show up to complicate things when the party is dealing with a cloud. Since the allips are undead, the gas doesn't affect them at all. Such an encounter is far more deadly than either the cloud or the allips alone, so a +50% ad hoc XP award is in order.
