I saw that Heroes of the Storm has a big 2.0 relaunch coming and I was checking it out. It turns out they are adding Cassia, the Amazon Warmatron, as a playable hero in that game. The description of her skins tells a little about what happened to the Amazon after Diablo II: Lord of Destruction, I don't remember if this was ever detailed before.
After shattering the Worldstone, the young Amazon Cassia had changed.
She had seen hatred, terror, and destruction firsthand. If the Askari
were to survive the coming darkness, they needed an army. She would
begin their training immediately.
After her victory against the Prime Evils, Cassia ascended through the
ranks of the Askari to become their most legendary commander. The
Warmatron’s battle armor is a gift from Queen Xaera herself.
