The Vostarg Lodge is a Fyreslayer Lodge located beneath the volcanoes of the Cynder Peaks on the sprawling magmahold of Furios Peak. They are among the oldest of the those wthin the Realm of Aqshy, descended from the legendary Vosforge and the only scions to still bear the name of Vostarg. They have a reputation as brutal mercenaries and fearsome warriors that stretches far beyond the borders of their domain.
In the Age of Myth, the lodge pledged to defend the city of Shadespire in the Realm of Shyish, when the city was banished to the void between realms they felt their oath was unfulfilled. Since then hundreds of slayers have ventured into the ruins and sought entry to the hidden city in order to facilitate its return, so far none have succeeded or even returned.
At the beginning of the Realmgate Wars, many Skaven under the command of Gnawmaster Rikfang of Clan Rictus invaded the lodge to claim captives to sacrifice to his patron Verminlord Kratterklaw. Although the chittering horde manage to steal the son of Runefather Bael-Grimnir, he and his outraged fyreslayers quickly pursued them and took brutal venegance. Rikfang escaped - leaving Warlord Driptail to face the wrath of the father in search of a lost son. 
As they took stock and released those captives that remained, the Hammers of Sigmar, Stormcast Eternals arrived and were confronted by a mass of angry fyreslayers. Despite the potential for violence, the two forces met and eventually agreed a brief alliance over a flask Magmalt ale - the Fyreslayers would lead the Stormcast to the Bloodkeep and even burn a path into that brazen stronghold from beneath.
