Netheril

Netheril is a fictional location in the Forgotten Realms campaign setting of the Dungeons & Dragons fantasy role-playing game.

However powerful humanity can be, there is one opponent it can never face and win: hubris.

The magocracy of Netheril was one of the ancient human empires of Faerûn that lie in what is now the (magical) desert of Anauroch. Netheril was also the home of the most powerful wizard who ever walked on Faerun, Karsus, who could cast 12th level spells (although he cast such a spell only once, and it was his last spell ever). The Netherese also created powerful artifacts known as mythallars, which allow mundane objects to become magical, dramatically changing the face of the Empire (or better said the face of the upper side of the empire, as Netheril eventually became twofold: the "have", High Netherese, and the "have not", low Netherese).
