Tir Asleen was considered the greatest of all kingdoms on Andowyne, dotted by beautiful and inspiring castles on its highest hills. Rulers maintained control for nearly a thousand of years magically creating an environment in which the natives wanted to live in peace and harmony. Other buildings housed immense libraries, where sorcerers and philosophers studied side-by-side.

The peace came to an end when Bavmorda rose to power and froze Tir Alseen in stasis, sealing it off from outsiders and forcing its inhabitants into a state of suspended animation.

Cherlindrea sends Willow on a quest to find Fin Raziel and to take Elora Danan to Tir Asleen where a good king and queen will look after her. When they arrive at Tir Asleen, they find that all of the people have been turned to stone.

A great battle occurs there between the Nockmaar army and the Galladoorn army, during which General Kael captures Elora Danan.

When Willow Ufgood and Fin Raziel defeated Bavmorda, Tir Asleen was freed from its captivity, and its people were once again allowed to roam its streets. Shortly afterward, however, Tir Asleen was razed during the Cataclysm. Nothing was left standing in its place, and the entire population of the kingdom disappeared.
