Now, don't panic, but in a moment you'll begin to feel a slight burning sensation...
In order to become a Catalurgist
, any would-be magic user must first undergo a dangerous surgery in which the patient's kidney is removed, and replaced with an artificial organ known as a Thymalladus
. Should the patient survive, they've got a long road to recovery in front of them, as they force their body not to reject this strange new organ.
Only once the Thymalladus has been accepted by the body, after about 6 months, may the Catalurgist-to-be take in their first Ichor
-- their "First Blood", and become a full blown Catalurgist-in-training.
