Editing Skein of Worlds:The Material Plane (section)

=== Magic ===
The range of ''Teleport'' is nowhere near big enough to move between even the closest planets (which would be about 200000 miles). ''Greater teleportation'' and ''teleportation circle'' are powerful enough to move between spheres. (Even spheres in distant systems are part of the same plane.) This isn't without problems though. Getting an accurate description of a distant sphere generally means having to go there, which defeats the whole purpose. It does allow someone to revisit a sphere they've been to before though, or to allow others to visit a sphere they've been to.

''Gate'', ''plane shift'' and similar spells are useless for direct travel between two spheres, but since the Astral Plane coexists with all spheres, it can be used to visit even unknown spheres. The Astral Plane isn't without its own hazards though.

There exist some spells designed specifically for moving between spheres. ''Note: insert such spells here.''
