The gates of Gehenna are guarded by two of the Seventy-Seven Devils: Astarte the Abyssal and Rostrum the Savage.
In Trails in the Sky the 3rd, Gehenna serves as one of the final dungeons that appears within Phantasma. There, Kevin Graham and Ries Argent confront Georg Weissman. There is also another, deeper level of Gehenna known as the Abyss.
Another area associated with Gehenna is the shaft near the main entrance of the Sun Fort in Crossbell was considered the path toward Gehenna by the D∴G Cult, from which they could turn away from Aidios' influence to side with demons by performing "rituals".
