I picture the Underhaven as something like Tyrael's man cave or something. Kind like Mar's room...except its a literal cave....talk about a low maintenance gal.

Mar's culture is rather primal compared to the Colleg and other residents. Her people liked to only change nature enough to suit their needs and rather adapt to their surroundings then change them unless needed. Heck, before the College, whenever she slept back in her home town there were more then just her in the room and you could barely move without slithering over someone. Sort of like what garter snakes do in winter where they seek out a nice underground spot and huddle close to one another for warmth, their bodies containing the heat better that way then individually.
