The Aether is roughly divided into Provinces of space each with a number of singular Shards and Shard Systems. Here is a list of some of them:

• The Frost Shepherds - A shared province full of history and import
• Home - The primary adventuring province in Rachel's jurisdiction(?)
• Welmet - The primary adventuring province in Cosimo's jurisdiction and home of the Welmet Voidspace station
• Nemedobur - The primary adventuring province in Declan's jurisdiction
• The Road - The primary adventuring province in Rew's jurisdiction

• The Empire of Blossoms - A shared province of faded Feywild might ruled by an empire of decadent elves who are content to have their mercenaries use the empire's advanced Arcana to do their dirty work for them
• The Blight - A province of torture and madness rumored to be the graveyard of gods
• Occulous - A province ruled by eye tyrants
• Dreamshards - A province of Fey Shards populated by the dead and ruled by ghosts who have forgotten that they no longer live

There are a number of Voidspan Gates instantly connecting several shards across provinces. Here is a list of some of them:

• Welmet connects to The Road by voidspan gate, giving adventures immediate access to that province without the need for a voidship
