Taru Hollola: Slytherin. A military strategist who uses her cunning to make plans while never being in danger herself, then quits for something more ambitious, is pretty much the most obvious Slytherin possible. Except for...
Trond Andersen: Slytherin. He's basically Taru with more connections, which he uses to blackmail people.
Torbjorn Vasterstrom: Slytherin. Are we seeing a pattern here? Torbjorn came up with the whole idea of sending people into the Silent World to recover books as a get-rich-quick scheme and was clever enough to actually get people to do it, including his own nephew.
Siv Vasterstrom: Ravenclaw. She's a scientist, and while she goes along with the book-finding scheme, it wasn't her idea and I don't recall her making the same kind of greedy comments her husband does about it.
