Lysas is an NPC in Dragon Age: Inquisition. He is found in Redcliffe and can be talked to for a different perspective on the rebellion and the future steps.
Lysas is a young elven mage taken to the circle at the age of nine. He is unhappy that the mages are being held responsible for the war when the Templars have also abandoned their vows and the Chantry.
He is, however, unhappy with the Tevinter alliance as it seems out of character for Fiona. He reveals that Alexius arrived in Redcliffe a couple of days after the Conclave, claiming he would protect the mages from the wrath of the templars.
