As dragon queen, she ruled the Spine of the World for centuries.
The human warrior Aihonen from the Ten Towns fought Icasaracht in an epic battle. She killed him, but in his last moment he successfully pierced her heart with his sword. Both fell into the lake Lac Dinneshere.
For almost a century, Aihonen's sword was embedded in Icasaracht's corpse on the bottom of Lac Dinneshere – until the sea spirit Elisia removed it to return it to Aihonen's descendant Jhonen in Easthaven.
Icasaracht had taken precautions against death:
- Firstly, she had set up a "soul gem" in her lair that would capture her soul in the event of her death.
- Secondly, she had laid two eggs, but used magical wards on them before they hatched to prevent their bodies from being inhabited by their own souls. She raised those two dragon bodies and magically preserved them. (Her mate disapproved of using their offspring in this macabre fashion, so she killed him.)
In the event of her death, Icasaracht's soul would automatically be moved into one of those two bodies.
However, this could not occur as long as Aihonen's Broken Blade was stuck in her corpse's heart. When the sword was removed, the soul transfer finally occurred, and Icasaracht awoke in her new body.
Now, she seeks revenge. During the events of the Heart of Winter expansion, she possesses the barbarian warrior Wylfdane, unites the barbarian tribes under him, and calls them to war against the Ten Towns.

At the end of the expansion, after her identity is revealed, you must take the battle to Icasaracht's iceberg in the Sea of Moving Ice and fight your way down to her lair to kill both her corporeal form and her soul gem.
