An imposing figure with a... Distinct body. Artificial in origin for those with the knowledge of artificing, however tainted by that which now resides within. A terrible soul, the architect of change, the one who destroyed an Empire with his actions.

This is the Lord of Change.

A reborn Archdemon.. and who heralds changes in the world when he is around. His mere presence corrupts the mind and weakens the lifestream.. Clearly, not just any kind of demon.
