The Blade of Mercy gift can be found during the Act 3 main quest Best Served Cold, unlocking Fenris' quest. Giving the sword to Fenris results in a restricted version, while choosing to keep it results in this unrestricted version that can be used by any two-handed warrior, including Fenris.
Of course, the Tevinter Imperium did not become part of the Chantry until well after its formation centuries later, so the first of these blades was created in 2:2 Glory as a gift from Archon Therion to his general, Lord Galineus, for battles fought at the height of the Second Blight. Since then many archons gave similar gifts and it is seen as a badge of honor within the Imperium—though more than one of these blades have ended up on the black market, either stolen or sold by the recipients when their family fell on hard times.Ironically, one of the four swords found impaled in the body of assassinated Queen Madrigal of Antiva in 5:99 Exalted (thus inspiring the Age of Steel) was a Blade of Mercy. It was a great sacrilege to the Chantry.
