This is all great stuff, everyone.
Yeah, my general thought was for the fighting styles and mindless rage, we might disagree on things, come into conflict on how to treat the dead, but largely be able to work together.
The undead was really the big issue, and I can see I was right to question it. Right now we're discussing reflavouring his summoning of undead to actually be Darkness Spirits (elementals, basically?) So that's one option.
As for the Zolan Zubar connection, since this is 13th Age, every character has a One Unique Thing. His is that he is a reincarnation of Varzor Kitor. (Who himself was an incarnation of Zolan Zubar I guess?)
(For reference, my own One Unique Thing is going to be that my Humakti died on the battlefield and was brought back somehow. He doesn't know how or why, and it certainly wasn't by choice, but it left the Rune of Life burned into his flesh. Life is now his personal rune, as well.)
My only real source of Zolan Zubar information that I've been able to find has been a wiki: https://glorantha.fandom.com/wiki/Zolan_Zubar
And they basically say this:
Based on other things I've found, this might be referring to bound spirits from Zolan Zubar? Something for Shamans? I'm not entirely sure. If this is true, though, then finding a way to reflavour the summons as something else would probably be best from a story perspective as well.
Any thoughts, besides just "Darkness spirits"?
Or am I wrong about Zolan Zubar?
