On the top floor of the Cordor Commons building, in the common area there is a Planar Explorer NPC that shows up randomly when you enter the room. I have come across him there three times now. He goes through a dialogue to accept coin to take you to somewhere in the shadow planes.
I do not know if this intended or a bug, so dropping it here - just in case he's not supposed to be visiting!!
