Ilythiir

Ilythiir was the realm of the dark elves during the First Flowering (founded roughly -23200 DR) and before the Descent of the Drow. It covered the present-day Shaar and Forest of Amtar. After the dark elves were banished from the sunlit realms, most of the remnants of the empire were razed by elves hoping to eradicate any presence of their evil cousins. Presently, the ruins of Ilythiir are the most sparse of all the ancient elf empires. Only two are known to exist, Athamault and the Citadel of Slime.
