|I'm glad to know you appreciate it. Elven architecture is a bit more sophisticated than yours.|

Tir ná Lia is the capital of the world of the Aen Elle and was governed by Auberon Muircetach. The river Easnadh runs through it. According to Ciri, the city has a look similar to that of Shaerrawedd.
Its buildings are described as light, open on all sides (thus resembling gazebos or arbours), seeming so airy, delicate and ephemeral that they actually look not like buildings, but phantoms of buildings. They are built of marble, alabaster, and malachite, and adorned with stucco, terracotta, and mosaics. There are many bridges and terraces, peristiles, cloisters and balconies, sculptures and monuments.
- The name Tir ná Lia is likely to be connected with "Tír na nÓg" (Land of Youth), which is the world of elves in Irish mythology.
During the third game the capital of The World of Aen Elle appears only once during a main quest. The Viceroy during that time is Ge'els who resides in the Palace of Awakening, formerly the Moon Palace, overlooking the Elven realm.
Contrary to description from the novel, the buildings of the city resemble those of typical medieval town.
