The Cataclysm of Ultana
Miquesh was a powerful Dragonborn sorcerer who raised the Pearnier family. His loyalty to Hector Peariner was the turning point for Hector as to why he outlawed slavery in his realm.
During the Fall of Avalar, he gave his life to keep them safe. He heard that Malegore Nine-Heads was enroute to the Group and he offered to provide the ultimate sacrifice; being a distraction for Malegore long enough for the group to make their escape.
