Religious event
When the elves began arriving in Toril through Fey Gates around -27000 DR, the dark elves quickly established the first large-scale elven kingdom to survive a world ruled by dragons. Ilythiir was an expansionist country, that started in the southern jungles and spread throughout southern Faerûn during the Dawn Age. It experienced another period of expansion during the First Flowering, during which it spread across the areas later known as the Shaar and Forest of Amtar. Ilythiir was a nation that institutionalized slavery. After Syòrpiir, Eiellûr and Thearnytaar fell in the face of Ilythiir's strength, the moon and wild elves were enslaved. Vhaeraun was worshipped among the Ilythiir above all other deities.
