Shadowbend

Shadowbend is home to a special location called The Reluctant Convergence. Here, the various realms of evil overlap ever so slightly with the material realm, forming a thin veil between worlds at certain moments. Most often only one overlaps at a time, but on extremely rare occasion multiple can overlap at once, causing unstable portals in the lower realms to draw unsuspecting monstrosities, demons, and undead into each others realms or our own. One moment they're walking along in endless tunnels of darkness and the next they emerge into an adobe style village built into a mountainside.

Someone or something stops them all from spewing forth and wreaking havoc. The sun and wasteland conditions of The Cauldron aren't appealing to most who emerge so unwillingly from the convergence, and those that would relish the terrain are somehow halted. Either a paragon of goodness keeping them contained, or perhaps an evil force funneling them elsewhere for some sinister purpose.

Either way, Shadowbend isn't a destination marked on any maps, and it isn't a welcoming place. Though the rare vile human will find there way there to attempt to make a deal with a devil, rarely does it go in the mortals favor.
