@CrazyZleric thanks , even if you got the name wrong!

might be a thing for them to have broken into the old abandoned house in the SW quarter. would provide rest and a cage for the celestial faction, though it is right on kantheas doorstep.

there are secret tunnels into the sewers from wild lands, rat holes, twisted caves, effluvial lake and ruins.

along with portals and the underdark there are actually plenty of ways about the place I think, they just aren't necessarily easy.

the thunderholme link I can see the issue though, might be worth sticking another portal to there or set up a boat from captain nickers in sewer bar?
