Ingeloakastimizilian

Ingeloakastimizilian was a White Dragon that lived in a region of the Reghed Glacier known as Evermelt. She spent most of her time sleeping on a bed of ice that covered her hoard. She was killed by Wulfgar after he threw his warhammer Aegis-fang into a stalactite that fell and impaled her, so that he would have a trophy that would enable him to challenge the leader of his barbarian tribe to a duel.

The barbarian tribes north of the Spine of the World mountain range called her Icingdeath although this name is more commonly associated with one of Drizzt Do'Urden's scimitars.

Ingeloakastimizilian is the only White Dragon (canonically) known by name.
