I was wondering how people use the undead animus to get the house guest of undead but when they place them in their houses they aren’t the ghostly figure but a regular human. How is this possible?
I've been experimenting with this myself. It seems to work primarily on human ghosts from Dragonspyre, like the Wandering Wizard or Iona Pyrelance. Other transparent House Guests, like Grumish Greataxe from Krokotopia, Killmare Spiritwalker from Zafaria, Thunderfin and Yogash from Celestia, and the countless other Ghost creatures across the rest of the Spiral seemingly cannot be made opaque.
I think that this should be addressed when revisions to Castle Magic happen again.
