Sigil is a city-plane and is where most astral travellers find themselves, at least temporarily. The city has accommodations for people of all races, and goods of remarkable quality and power. The city sits on a series of large, free-floating spires in an otherwise featureless gray void. The city is notable, however, because of the incredible amount of portals littered around the area. Some portals are open, some require keys, some lead to the material plane, some lead to other areas of the outer planes, some lead to Elysium or The Hells themselves.
