I don't want Halsin as a companion because by all logic he'd be way too powerful for our party, but I actually really like Nettie and think she'd make a cool companion. She's his apprentice, so it'd be reasonable to have her on the team. Plus there aren't enough female dwarf characters around.
Good idea! I haven't thought of her, but she would actually fit really well as a companion, given the severe lack of dwarves thus far. Also its true that Halsin should be much more powerful than the party... No idea how this would be solved if he turns out to be a companion.
