The Moonbeam Roads are the ethereal pathways through the Multiverse, leading between universes, from world to world.
The roads pass through the Higher Worlds, and run between the universes. A traveler upon the Moonbeams can percieve the entire Multiverse around them.
Stormbringer has shown the ability to cleave a pathway to the Moonbeam Roads.
The greatest known navigator of the Moonbeam Roads is the Rose Von Bek.
