Cadenero, maestro de demencia

Chainer was a pit fighter and a dementia caster for the Cabal under Master Skellum. As a cabalist, the name "Chainer" was a nickname, while his real (secret) name was Mazeura. Chainer was the first person known to have found the Mirari on Dominaria. Initially he was able to resist its lure, but ultimately he became obsessed with it and was consumed by its power.
