Grand Mage Yasha Coliatti is the head mage of the Arcanium. She became head of the Arcanium in 1012 AC.
Yasha grew up in Lagiorni but fled with her parents to Panere during the civil war. She grew up tending the markets with her family to make ends meat. While most high ranking members of the Arcanium join at a young age, she joined much later at the age of 40, being recruited by the previous head of the Arcanium, Grand Mage Suria Sorio. When Suria died, she left Yasha as her heir.
