Dorion was the last of the Neurdagons to take up the mantle of Dragonlord as part of the Dragonlords. This was only an honorific, however, and he had no bonded dragon.
At some point in the last few centuries, Fort Dorian was named after him.
Dorian's sarcophagus and tomb at the Necropolis at Telemok was looted and damaged in the recent past, though the Oracle's Chosen did their best to help clear and fix it.
