I remember learning of a portal system that existed throughout hell, and figure there might be some near the ruined city. It had clearly been a large and impressive city at some time far in the past, after all. It would make sense that they would have one of the portals for armies to march through and conquer worlds nearby.

Eventually, I find what I'm looking for. A set of mysterious and imposing arches, large enough for dozens of demons to march through at once. Seemingly sensing someone's presence, the strange lightning in this place strikes down and starts to activate the portal. I have no idea what world I'll end up in, but at this point, anything is better than here.
