Zeos

Zeos is one of the sixteen Gate Towns in the Outlands plane. Zeos connects the Outlands to Limbo via a rift that randomly appears in the area. A teleportation circle inscribed on a spinning earthburg connect Zeos to Sigil. Zeos was once populated by githzerai and modrons, but has been relatively empty since the Calamity of Gith. Recently, a mile-wide astral vessel in the shape of a cube has been ripping through the Limbo rift. Swarms of robotic worms are leaving the craft and travelling to Sigil , infecting every modron encountered.
