Of all the faction types we have:
Court People
Daedra Person
Generic_Group Region
God Subgroup
Group Temple
Knightly_Guard Thieves_Den
Magic_User Vampire_Clan
Official Witches_Cove
Do all guilds fall under one of these? Particularly I'm looking for "Evil" or morally wrong guilds to be part of like Dark Brotherhood and Thieves guild but would like to involve all factions with association with those particular guilds. If anyone could help me out with these I'd be grateful. I can't find a list for Faction types anywhere online. Would Dark Brotherhood fall under Thieves_Den or would it be a subgroup?
