The Parrots are looking out for you
The bottom of the planes... the frozen end.
Tartarus is not only home to lava and the like but you might find a mine or two there too
Home of witches and lots of evil... this frozen swamp is packed with monsters.
Some planes have portals straight down to the next plane. (in other planes you just jump)
Limbo is an unusual place. filled with the lost, the waiting and the things they held on to before death.
