Blackmoor Multiverse

[Havard]

An interesting tidbit about the percied planar structure of Blackmoor can be found in the Blackmoor Player's Guide p 175:

Mithgilivyr Goss theorized the existence of the following Planes:

Six Elemental Planes, Ethereal Plane, Astral Plane, Plane of Shadow and Plane of Time

Expanding on this list from various Blackmoor Sources:

The Six Elemental Planes

The Transitive Planes

Other Planes

• Plane of Time (Entrem) - More details
  
• The Ephemeral Plane (MMRPG's version of the Fairy Plane)
  
• Earth/Laterre (See Dave Arneson's WWII adventures, Tom Webster's Atlantis, possibly connections to Braunstein, Brownstone, DA's Napoleonics Campaign)

Other Realms

• The Dweomer Realm (MMRPG) - a kind of Blackmoor Underdark - More discussion
  
• Age of the Wolf - Accessible through Time Travel
  
• The Galactic Realms (Home of the Federation and the Empires from Jon Snider's Stellar VII Campaign)
  
• Old Alphatia - Possibly a dead world in the Galactic Realm. My idea is that Alphatia is settled by Blackmoor Elementalists.
  
• The Hollow World - If the planet is hollow, what's going on within it?
  
• World of Greyhawk (aka Khoronus' Blackmoor Copy)
  
• World of Mystara - Accessinble through Time Travel
