Dagnirion's Enclave

Dagnirion’s Enclave is a foreboding earthmote that is roughly a mile in diameter, which floats roughly a mile above the ground, over the Forest of Shadows. It was the initial erection of Dagnirion’s Enclave that caused the Forest of Shadows to become an eerie twist of it’s former self, in fact. The aptly named landmass is the home of Dagnirion, the powerful Drow magician.
Dagnirion created the enclave to act as his home base, of sorts. The magically flying landmass is similar to the flying earthmotes that hover above the magical city of Cymru. This is because Dagnirion created the magical item keeping his home aloft by studying the magical practices of the magicians of Bai'el, the extinct culture that the magicians of Cymru hailed from.
Dagnirion himself rarely leaves his enclave. Instead, he normally works through intermediaries- primarily Nogardama, a Black Dragon bound to the powerful Drow archmage and Odeon, a priest whom Dagnirion rescued in the Plane of Shadows.
