Simrrax

Adult or Young Adult Magma Dragon from Taldor. Estimated to be between 100 and 200 years old. Attacked Kozan during a tournament, before heading out to sea. (1st of Erastus, 4696). Seen in a vision five days later by Leah, talking to someone unseen in a forest, speaking Giantish. The translation is rough, but they were speaking of some kind of powerful fragment and the unknown speaker being protected from fire.
7th of Arodus
Leah informs party Simrrax is suspected to be on an island in the Shackles.

Lair

Laired in a volcano two and a half days' travel from Kozan. Attended by kobolds who seemed to be upset by the dragon leaving; they were starting to destroy carvings on the caldera expressing worship for the dragon.
