Thaeravel

Thaeravel was an ancient realm of sorcerers in what would become Netheril.

Geography
Thaeravel was north of the Windy Plains, east of the Flats and south of the Shinantra Mountains and the Hidden Lake. After the plains turned to dust the area became known as the Quarter of Emptiness in the Sword of Anauroch.

History
The realm was founded around -4300 DR with its capital of Rasilith. It drew the attention of Netheril's ambitious arcanists and was destroyed in -3392 DR, with their arcane secrets torn from the minds of its magicians.

As Anauroch expanded south after the fall of Netheril, the area became an especially harsh and lifeless region of the Sword known as the Quarter of Emptiness. Rasilith became home to an underground colony of phaerimm who enslaved a tribe of laertis.

The realm of Thaeravel fell into legend, and it was speculated to be the original homeland of Netheril, rather than an early victim of it. Around the, the Brave Blades adventurers delved into a sorcerer's spider-infested tomb there, finding clues that led them to the Floating Tower of the lich Ondil.

The return of Thultanthar in 1372 DR led to the extermination of phaerimm, and Rasilith was resettled with Bedine people who were acculturated to the Netherese.
