The Lustrare River Valley resides in Ghyran to the far north of the Heaving Peaks of Invidia and north west of the Sickling Sea on the northern continent of Maz’Talik. Protected by a mighty ring of Highlands and Mountains, the valley is a natural haven for life and is broken into three different vast regions: Northern, Southern and Western regions. The valley is home to mainly the Lustrated Temple Host though both Sylvaneth and tribal human settlements also flourish here. Already a wild ecosystem its jungles, marshes, grasslands and even its large desert have grown wilder still with the help of Realm Engines being powered directly by the Lustrum Node. Even with the mighty natural defenses and devastating armies of its inhabitants is not enough to deter outside forces from wanting access to the valley. Skaven carve out fortresses in the mountains to the northern edge and raid Green Ridge Pass disrupting trade and communications. Nurgle Breaches the mountain range to the far south (not pictured) hoping to exploit the Evergrowth Plains that lie south of Tlacopan.

The Lustrare River Valley was named after the Lustrum Ley Line that it rests upon and is thought to be blessed by the Old One Tzunki by the Lustrated Temple Host. The River is considered sacred to the Seraphon and to the Huron Creek Tribe, it is both a source of food and ritual importance.
