Fireheart was a Hive queen.
Biography
On Queen Fireheart's hive, the Storymaker Salt saw a version of the tale of Dusk and Dawn and the Consort Rapid who betrayed them. A thousand years later, Salt performed this tale to expose the traitor Bell, who like Rapid, had poisoned a ship and forced it down on another world, killed blades, and clouded a queen's mind.
