Ileuthra

Ileuthra was a brass dragon that heeded the call to Protanther's council to discuss the menace of the Cult of the Dragon and Tiamat during the time of the Tyranny of Dragons.

History
Ileuthra was a very ancient dragon, always in search for knowledge and more challenging games. He long wandered the planes in his research, and legends said that Ileuthra lived for a time with Oghma, the god of knowledge. For his experience, he was chosen to represent his kind in Protanther's council. A band of adventurers sent by the Council of Waterdeep convinced him to ally with the humanoid races to stop the Cult's plot.

Personality
Ileuthra saw good and evil in equal measure among the lesser races. He believed that it was individuals that made the difference between victory and defeat, and a trustworthy individual could be followed, even by dragons.
