An illustration of a halfhuman turning into a human.

Convertions were a ritualistic set of operations, that'd ultimately redesign a humanoid's Chromosomes, eventually turning them into an entirely different specie. It's one of the most painful biological processes that can occur and is only executable with the use of Alius. Convertions were usually executed by cult-like groups in order to convert anyone into the race, which they'd find superior. The methods are most noticeably used by verums throughout history. 

Convertions were mostly forbidden throughout history, although certain factions such as the Verum Kingdom are examples of civilizations that encouraged the operations.
