The Chasm didn't truly arrive in Nskanetis until Auli'kuris was dismantled.
This statement might come across as contradictory, and it should. Chasm Fogshards have always sprung up in the soil of Auli'kuris due to its arcane energy, implying that Anarchic Radiation sleeps in the soil or the magic of O'urtnx itself. Nskanetis Herself has been theorized to be the same being as the legendary horseman Death, lending another connection to the Chasm. It's true that there have been inherent ties to the Chasm peering into our world for as far back as most scholars can find.
The destruction of Auli'kuris and the formation of the Fogshard Mine, however, formed a permanent hole in Nskanetis's leyline that the Chasm rushed in to fill. There is an almost seamless transition in the deeper mine shafts that when entered, leave this reality entirely. While this phenomenon is being studied, professionals are stationed on site to guide the public away from the Mine.
We do not have enough data on this phenomenon to tell you where you will wind up and what you will find if you enter the mine yet. Please consider your safety first and foremost and stay out until we have more information.
