To be accurate, like most of the other Faction leaders, he's currently sealed away to keep Trihexa sealed under a seal that will sap the beast's power over time so it'll be weaker when the seal breaks and it's freed again.

So he's alive, but he's also pretty much in something like a coma till this seal is undone, and EX implies that the seal is still up if I've got my information right.
