I'd like the name to have meaning rather than just be "cool", but I'll settle for something like that if that's what everyone else wants. On a similar note, I'd prefer not to have Cauldron in the name, but a subtle reference might be fun. Maelstrom can fit that idea if you think of it as Cauldron rather than a whirlpool. I looked into the name and—according to wikipedia—it literally means "mill-storm" or grinding current. I can see that fitting Cauldron, whether referring to lava, its history of flooding, or another interpretation of the word "current." The shape of Cauldron also fits my idea of a maelstrom.
This may sound silly, but I actually liked "The Church of Dead Thieves" and "Bearclaw." They both made me chuckle. If we go with the latter, we need to have a specific bakery moved to our merchant area. I could also go with "Ascension" since Kor's ultimate goals can be interpreted as something like that.
