Tyra

Tyra was a female young adult black dragon who dwelled in the Vast Swamp in the mid–14th century DR.

Relationships
Tyra was the spawn of Skurge, the great dragon of the Tun Marshes, and the clutchmate of Despayr. Through Skurge, both Tyra and Despayr were direct descendants of the mighty Thauglorimorgorus, the Black Doom, who once ruled the entire land of Cormyr.

Lair
Tyra and Despayr dwelled within the Vast Swamp. They typically hunted for prey within its confines, but by 1367 DR they had started raiding into the settled lands of Cormyr beyond.

History
When Despayr hatched from his egg, revealing glowing runes across his scales, Tyra and her mother were shocked by the sight. When it became clear he could not breathe acid or wield magic like a typical black dragon, they spurned him and treated him unfairly.

Nevertheless, both Tyra and Despayr made their lairs in the Vast Swamp. When they began to raid outside its edges by 1367 DR, several adventuring companies made expeditions into the swamp with the aim of slaying the dragons and/or stealing their treasure hoard. However, most disappeared, few returned unharmed, and none were successful. Tyra was recorded to still be alive and well in the Vast Swamp around 1373 DR.

Ultimately, it was a lizardfolk tribe calling itself the Dragonslayers that claimed the credit for slaying Tyra. The lizardfolk then settled in her lair.

However, Despayr, now corrupted by Shar's will, had a dream of his sister's death to the Dragonslayers, and of her unguarded hoard. Following his visions, Despayr came to Tyra's lair, massacred many of the lizardfolk, and enslaved the survivors. He then took her lair and hoard as his own, before he was visited by Esvele Graycastle, who retrieved from the treasure the shadow shard. With this, Despayr transformed the lizardfolk slaves into the first of the Shadowscales by 1374 DR.
