So I was reading a part where Roxy is making a ball of spikes to repopulate the troll population and help the condesce take over because if not Jade would kill her over and over again. But. Wouldn't she die completely because it would be just and heroic? The justice would be her preventing the race from it's population, and the heroic part would be her not letting the condesce have an army.

A godtier dies permanently is the death is Just or Heroic, not both. Roxy would revive if she was tortured by Grimbark Jade because she’s not evil so killing her wouldn’t be Just and getting your organs teleported out repeatedly isn’t very Heroic. The Condesce wanted Roxy to summon the Matriorb because the troll race is endangered and she doesn’t want them to die out completely. Also, she wants a new population to rule over.
