So I really only play Tev as the canon Deathlord whenever what I’m writing calls for it. (basically when whatever comic or plot I’m doing wouldn’t make sense otherwise.)
Otherwise he’s a Deathlord but not the Deathlord. I figure that he got a promotion because Shit is Going down (and Koltira was in Gay Baby Jail,) but he’s not the head of the Ebon Blade because he’s not about that sort of paperwork, or really answering for the ebons to outsiders. And since there are multiple Highlords i don’t see why there can’t be multiple Deathlords too. Plus that way he had the freedom to track mud all over the paladin order hall when they tried to recruit Tirion (it also meant that he was complaining that this idea was stupid a fuck all the way there.)
