Kurald Thyrllan, or Kurald Liosan, was the elder Warren, or Hold, of Light. It was inhabited by the Tiste Liosan, with the city of Saranas as its capital. Kurald Thyrllan gifted the world with Light and Day.
Beak observed that Stormy and Gesler were "reforged in the fires of Tellann". He then went on to say:" Telas, Kurald Liosan, the fires, the ones dragons fly through to gain immunities and other proofs against magic and worse".
