I feel like the contest of champions isn't going to be like what we expect. It got me thinking about who Taravangian would choose as his champion. Rayse may have been grooming Vyre, but I don't think Taravangian will do that.
It seems to me that Sanderson is implying heavily it's this new El dude, from what little we know he's a Fused that fell out of favor under Rayse and the other Fused since he has great respect for humans, but that aligns him with Taravangian. That might be a little straightforward for him, but we also know it's less about the contest than the leadup so there is still plenty of room for swerves.

I definitely did not forget to put the 2020 GOTD Guru winner, azuarc in my sig!
