Outer Planes

Outer Planar Pathways

Yggdrasil: roots reach Hades and Pandemonium, branches reach Elysium, Beastlands, Limbo… and an infinity of other places

Styx: unpredictable, no one knows its start or end, but touches the top layers of all lower planes

Oceanus: “Its headwaters lie in Thalasia, on the plane of Elysium. From there it flows through all of Elysium’s layers and eventually breaks through the boundary between the planes, passing through the top layer of the Beastlands. After this, it crosses another boundary and enters Arborea, passes through the first layer, and finally disappears somewhere in that plane’s second layer, Ossa.”

Mount Olympus: also some Powers’ Realm, connects to Arborea and has veins to Gehenna, Carceri, Hades and some prime worlds.
