Angerboda the Great Hag.
It is a common name in the Jotun mythology, so it's reasonable (if slightly confusing) to have it turn up on non-hero gygjas. The regular vaetti hags can get the name also. Just rename your units, or remember what's what
As Jotunheim I always take misfortune anyway, and have never gotten the hero Version of Angerboda in a real game, powerful tho she is.
