Malxas
Living Infernal Stronghold
Malxas is a living Infernal stronghold who bargains with mortals seeking security and power. Evangeline says it accepts offerings for fortresses built on sacrificed bones, but never keeps its promises. Its power also holds the Infernal Spire in place; when the Hero and Aranx weaken it, the tower begins returning to the Infernal Realm. A later Infernal appearing as Malxas is, according to Aranx, someone else who has recently transformed.
