The Nether Fountain
The Nether Fountain was all that remained of an anti-magically radioactive meteorite, the Vile Comet, that crash landed onto Legere nearly 500 years before the Demon Wars. The meteorite was comprised of Ugrite, which poisoned the surrounding area, forcing life to twist and mutate, culminating in a harsh wasteland where only a few people dare to live. The meteoric material itself remained deep within the Nether Fountain, continuing to pour out deadly radioactive gases and maintain the poisonous environment.
The Nether Fountain was the home of the Moonbeast.
