"The Will of Ashan" - "Heart of Darkness" [2nd campaign, 5th mission]

Not a hero, a ghost is a slain Knight. Therefore, his daughter is also a human. Out of curiosity, I visited all 3 portals with reloads.

Necro, which heroes did you put in the circles? You need to put Ornella and three Necromancers bought in the tavern.
