Synnoria

 is an ancient elven kingdom hidden in the mountains bordering the Myrloch Vale in Gwynneth, one of the Moonshae Isles. It is covered in a powerful mass illusion spell so that, if viewed from above, it simply looks like a continuation of the surrounding mountains. Overland, there are three mountain passes that lead into the realm, but they are narrow and full of false trails and gorges so that they are very difficult to get through without very detailed directions.

Synnoria boasts only a single real settlement, the city of Chrysalis, mostly abandoned since the Retreat and the low birth rate of the local population, known as the Llewyrr. Legends always told of a reversal of this turn, and though the Llewyrr always doubted this legend, it proved true when the entire island of Gwynneth was taken over by noble eladrin leading to humans being banned from it's shores in 1375 DR.

It was attacked by Ityak-Ortheel in 1365 DR when Malar and Talos sent it through a portal but the elf-eater was defeated and banished back to the Abyss after it had destroyed Argen-Tellirynd, the Palace of Ages.
