Corruption

Information
Corruption is a sickness that those who have the skill of sorcery carry, it has 2 stages.

In the first one, corruption is in the asleep stage, meaning that the sorcerer can't spread the sickness even if they touch other living organisms. This is because the sickness has still plenty of soul from the sorcerer and has no need to activate the last phase.

Corruption activates its final stage when it feels that its host's death is near, the sorcerer could dying because of a death-blow or just of age, sorcerers don't exceed the 40 years of age. In this stage, until the sorcerer dies, every living organism they touch will become corrupted, and that organism's soul will also be consumed by corruption, and so on, leading to a further spread of the sickness.
