Suggestion Title: The effects of Corruption and the Taint.
Description: Two effects that are very eminent round Obelisks and in the Abyss are Corruption and the demonic Taint.
Corruption more directly affects the land. It drains all life from the soil turning it into a strange mud, reeking of death and decay. Corrupted land can be reverted with magic or Druidic power, slowly returning the life to the earth. The effects on Humanoids are very slight. You would have to spend days, weeks or even months before the Corruption can manifest itself in a living being. Although, it is much more difficult to revert the effects on corrupted tissue. Very few have been foolish enough to stay within Corrupted land for any serious length of time, but after a while, they go insane, unable to control their own bodies and unable to live out with the corruption. The eventually become a "Husk". A human form whose soul has corrupted and gone to Azerai himself. These Husks are sometimes found following their demonic masters, adhering to their every command.
The Taint is a disease caused by extreme exposure to high density corruption. Fortunately, such masses of corruption can only be found in the deepest groves of the Abyss. The very unfortunate few to have experienced this suffer greatly. Their soul is also corrupted, but to such a level that it becomes a demon soul! Most of the afflicted appear like themselves in most ways to begin, but eventually go through a slow demonic metamorphism and become Demons themselves... These new Demons are much weaker than their pure-bred counterparts, but are still superior to their old selves in almost every way.
