The Fugitive's Mantle is a light armor that once belonged to Malcolm Hawke during his mercenary days, before he met Leandra. It is available in Dragon Age II after downloading the Mage Item Pack DLC.
Background
Malcolm Hawke ranged the breadth of the Free Marches as he ran from the templars who pursued him. He often posed as a mercenary, and his substantial martial skills easily secured him positions in different bands. On one assignment for the Crimson Oars he was sent to Kirkwall, the seat of templar power in the region. He had every intention of staying there briefly, but fate had other plans.
