 * First recorded battle between the sharn and the phaerimm.


 * The Host Tower of the Arcane is created when the Arcanist Melathlar flees to Illusk from Netheril. He sacrifices his life to create the structure and power the magical wards that surround it.
 * Melathlar's older sister Khaela founds a subterranean Netherese colony to the northeast of Illusk as a final hidden home for her fellow refugees, just in case Illusk should fall to pursuing phaerimm. It is named Khalusk.
