In all honesty, this sounds just fine to me... the whole totem expansion just doesn't really match the theme. It's a strained metaphor¹. And as for the "people might be offended by christian themes," uhm, guys, they're already offended and left when they saw the whole monastery theme.

Update: Uncle! Uncle! Yes, I do know that it was tilly who was complaining about overly christian themes in the suggestions for new levels.
For reference, I am a significantly non-christian person. However, I still think that we are already on a christian theme, so why are people getting pissy now?
On the other hand, someone else in this thread suggested some religious titles from some other religions. I'd personally be just as happy if we used some of those, if the community decided that we really do need to add more levels.

¹ Yes, it's already strained, but this is a totally orthagonal strain.
