The problem with this being that it isn't just some other realm. It's one GM and Garret. So Gustav can't treat it as some collection of human nobles. It's literally one noble Gustav would not have anything to do with now, and some being that Gustav would not talk to unless he were pressed by the rest of Sanguis Astroism, seeing as he knows nothing about Haktoo.
Actually is Garret and a collection of Zuma nobles. The fact that one GM plays the Zuma nobles is OOC information now isn't it.
