Rotspire

The Rotspire is a stone and bone tower that floats over a crater in a mountainous region. It is about 600-700 feet tall, though does not seem to be entirely complete. It is the location of Nox's true lair and where he intended to perform the ritual to become the only Ascendant Dragon. 
It consists of Some Floors. Floor we arrived on also had Haaken and the melee dudes, second floor had Anarith and her mages, third floor had Chirak and their zombies. The fourth floor was labyrinthine and contained a chapel that had been left to rot and be consumed by flora. (For some reason Saiyo and Matsumae were here.)
== Notable NPCs ==
=== Anarith ===
Anarith the Supreme was a mage working for Nox in charge of the bulk of the magical forces under him.
=== Chirak ===
Chirak the Unhallowed was an unliving mage who experimented in the undead and was in charge of the undead forces that were not dragons. He apparently created Hedemora, and was upset that the party had destroyed him. When Chirak was killed, the party had to remove the crystal embedded in his spine, and destroy it in a consecrated location to prevent him from possessing a new body. 
=== Haakan ===
Haakan the Ravager was in charge of the standard military forces for Nox. He was a very large man who claimed to have had a slowburn relationship with Anarith. He was devastated when he learned that she had been killed, and attacked the party in revenge. The party spared Haakan because they're a bunch of bleeding hearts. He miraculously survived the collapse of the Rotspire and was taken to the Platinum Disc I hope.
