Third planet from the sun in the system called Realmspace, orbited by the moon named for (or actually being?) the goddess Selûne.
The campaign focuses on the continent of Faerûn, but it hosts other continents (themed to other genres):
- Zakhara (think 1001 Nights/Arabian adventures)
- Kara-Tur (think Asian themed adventures)
- Maztica (think Aztec/Mayan/Incan adventures)
- Katashaka (think African adventures)
- Osse (think Native American/Austrailian Aboriginal adventures)
- and others - like Anchorome Archipelago and Laerakond.
