Toril
For all intents and purposes, Toril is the primary world (i.e. planet) of the Forgotten Realms campaign setting for Dungeons & Dragons, but with my own homebrew spin.
NOTE: This Toril may not necessarily be the Toril with which players are familiar. Rules, places, lore, errata, ephemera, creatures, and even historical events--pretty much anything--is subject to modification from the published material for use in my D&D Campaign(s).
