[Source] Azar Javed is a Zerrikanian sorcerer and alchemist who took part in Salamandra's attack on Kaer Morhen. Initially known only as the "mysterious mage", he and the Professor were the main instigators of the raid on the fortress and were uniquely responsible for the theft of the witchers' secrets. Spoiler warning: Significant plot details follow. Ultimately we find that Azar is one of the highest ranking Salamandra, but not the ultimate leader. While he is certainly responsible for the mutants plaguing Vizima, he is only following a grander plan, conceived by someone else.
