Ash Mason is a construct built by Dr. Darien Mason. Ash came to be from a failed attempt to save the life of the demon Bloodwing Dragonash. A shard of QliSteel Gears soul-chip that had lodged in Bloodwing's sternum and enchanted the bone to become a soul-chip itself, where Ash gained sentience. The original body was disintegrated during a battle with Jeremiah Mason, but the soul-chip survived and was installed in an entirely robotic frame.

Ash is currently a ward of Frau Annechen Lowey and an employee of the Consulate of Europa, functioning as a Consular Liaison to Steeltopia.
