Another DIABLO 3 pony… however, Xazax isn’t present in the game T.T
He was my firts thought, after I saw Chrysalis, because he is shape-shifter too. He is a mantis-like demon in the service of Belial, Lord of Lies. The greatest figure in “Legacy of Blood” from Richard A. Knaak :D
In an imagined story of mine Xazax tries to steal a relic from Canterlot during a mage-conference, where Twilight is invited too. When Twilight figures out, that something is wrong and begin to investigate, Xazax finds her strong magic interesting and takes her along to Hell, into Belial’s palace.
