Once a settlement of those who fled the Aglorexi Empire, this refuge was claimed by the Torvilian Relief force as their base of operations during The Ravaged Coasts campaign. They named it 'Yndrinienburg', after Yndrasta, the slayer of monsters and patron of many worshippers of Sigmar in Ghur.
Over time, Yndrinienburg has become a fortified hub for the free peoples with a port, Sylvaneth embassy, and two minor Stormkeeps of the Obsidian Watch and The Black Aegis. The city is a gateway to The Gnaw, with many warbands making this their final stop to stock up supplies before entering the most vile and dangerous place in The Mortal Realms.
While largely still a ruin, the city is bustling with soldiers and all the various services to keep them fit and occupied. At the main streets, many taverns and armories can be found, where the most ambitious merchants trade their wares. From the darker alleyways, gambling dens and smuggling rings spring up like weeds. The greatest source of income is however the Emberstone mining. The fuel that keeps the mechanical titans of Hammerhal going lies here for the taking. It feels ironic how the Skaven are thrawted by the many fortune seekers who are more than willing to step over corpses in their journey to riches.
Many who stay longer in Yndrinienburg notcie that while the city is accomodating to many of Sigmar's allies, it has a quite strong contempt for the students of Tyrion and Teclis. This animosity was stirred when the Lumineth of Xhensia joined the Kruleboyz in an attempt to place their glyphs of protection and shelter this part of the Mortal Realms from the Skaven onslaught. While they were succesful, their treacherous act has shunned them from this seat of Sigmar. The relations between the Lumineth and the other forces of order here are at the moment frigid at best, buy both will not yet raise their blades against one another at this dark hour.
Yndrinienburg is ruled by a joined council of Sigmarites and Stromcast Eternals. While the Obsidian Watch and The Black Aegis keep watch to the east and dispense justice, the Freeguild are in charge of internal affairs, such as building infrastructure, collecting taxes, and overseeing maintanence. It is no secret that the Sigmarites would like to have a voice in the war effort against the various forces surrounding them, but the Stormcast Chambers have rejected this request. This decision is based on the fact that the Freeguild showed little strength during the Ravaged Coasts Campaign, needing help from the other factions to keep their tiny territory. In the taverns it is said that the Sigmarites are plotting a plan to claim more power inside Yndrienburg, and that the first steps in their plan might soon be revealed.
