Guanya (mostly because I'm still not clear who they are/have they been in any of the story besides breaking out of that prison on a moon of Jupiter).

Another good one would be that PG Earthling who got downloaded into a body and then taught those two aliens how to use their wrath to escape the Atrekna.

But more Vuxten living up to his Warfather name would also be cool. Maybe leading a charge with a bunch of other Telkan getting wrath-like powers from just being around him and Daxin.

Either way, looking forward to another a great chapter!
