The Dying Sands of Athas
Donarr is the leader of a dragonborn adventuring party. He encountered the Icebreakers! first in the Fargrim Mountains, when he was challenged to combat by Olga the Awesome, who just wanted a drink of water. Olga beat him, earning Donarr’s respect.
Later, this respect won the party the information that Donarr and his crew were part of the Dragonborn Empire.
