This game takes place in Faerûn:

“Faerûn is a major continent on the planet of Abeir-Toril. The majority of official Forgotten Realms material covers this continent, and it has had more attention than any other area of the planet. The continent includes terrain that is as varied as any other. Besides the exterior coastline to the west and south, the most dominant feature on the continent is the Sea of Fallen Stars. This is an irregular inland sea that keeps the interior lands fertile and serves as a major trade route for many of the bordering nations.”
