Rannath

Rannath was a vale in Thay.

Geography
Rannath was a vale that ran from the northeast to the southwest across the Surague Escarpment northwest of Pyarados.

Flora & Fauna
Matter from other planes had entered the zone in, which made it a likely location for many abyssal creatures such as bodaks or bebiliths.

History
The Red Wizards of Thay slew Magister Baerzlus Anagathiir in that location after a long and extreme spellbattle in, straining the Weave to its limit and in fact fraying it somewhat. Though Azuth repaired most of the damage, visits from beings from the Abyss became a normal feature of the zone well into.
