Ember, it's in The Hidden Years hard back with Tyleet and little patch on the cover, but I coudn't tell you in which comics.
I think Zey and Door suffer from a Napoleon complex, a bumbling brain, and just enough charisma to wreck destruction. Small scale Hitlers along the line of thankfully deceased Idi Amin Dada. I've no sympathy or liking for those who, unable to find happiness, look for ways to distroy the one others have found. Two Spears at least was completely insane, and the harm he did to his tribe wasn't completely deliberate.
