Part 104: Orlanth and Aroka Again: Part VII
When Ortossi arrives for his battle with Aroka, he is surprised to see many Chaos creatures swarming towards him. "I knew this'd happen, now that there's Death and Chaos in the world," shouts the Storm Bull. "Go and fight Aroka, and I'll fight them off!"
Do as storm bull says.
Help Storm Bull fight off the Chaos creatures.
Run away.
Fight the Chaos creatures.
Ignore the Chaos creatures.
Yeah, the legends don't cover this at all.
