The symbol of Corruption

Corruption is the power of mutation, madness, deformity, and knowledge that mortals were not meant to know.

Corruption was the last Doom to assail the world, although none of the four Dooms followed too far behind humanity's mental awakening. Corruption stems from the search for knowledge at any price, regardless of whether others pay that price or the cost is personal.

The undiluted answers that lie behind the sky and past the rain are too soul-shattering for a mortal mind to contain. Wrecked minds fall most easily into Corruption, and Corruption wrecks minds, creating a spiral that spells ultimate ruin.

Corruption Mutant (Concept Art)

As Corruption is the Doom through which reality's secrets can be laid bare, its fanatics hope to summon up the Great Old One whose arrival is Earth's funeral.

Color: Corruption is black as a cadaver's heart rotting in the sepulcher.

Opposed: The sick insights provided by Corruption are often useful to the aims of Destruction and Deceit, while these two Dooms often enough serve Corruption's final goals. But Greed, the doom of analytical austerity, is Corruption's rival for the heart of humanity. Those trapped by Greed are too cowardly to search beyond the sane edge of reason and thereby become mere instruments of greater beings--cold calculation froze Greedy hearts and minds long ago.
