A Gelfling town during the late Golden Age.

The Age of Harmony,[1] also known as the Golden Age[2] was a period in Thra's history encompassing the nine hundred and ninety-nine and one trine after the end of the Age of Innocence and before the The Great Division.

It was during this period that the Gelflings, under the tutelage of the Fallen urSkeks, learned to tame nature and advance technologically. By the time of The Great Division, the Gelflings had managed to colonise much of Thra.[3]
