Xin-Edasseril was the capital of the Thassilonian realm of envy, Edasseril. It was initially located on modern-day Chakikoth Isle in the Ironbound Archipelago of northwestern Avistan, but was later moved eastwards, to the site of modern Peridot Isle, in -5402 AR. Although it shared the monumental architecture of the other Thassilonian cities, it was built on a disease-spawning marsh and was constantly plagued by attacks from ettercaps, ettins, and elven raiders. Its byzantine bureaucracy was filled with ambitious and ruthless administrators who cared more about their personal advancement than managing the realm effectively. Its final ruler, the Runelord Belimarius, oversaw the city and the nation from Palace Miasmora, where she kept her predecessor, Phirandi, entombed in a transparent coffin of force. Xin-Edasseril's other famous attraction was the Temple of Desna's First Dream, a shining edifice of glass, diamond, and magical force that seems to have disappeared or been destroyed, although some maintain that it can still be accessed through the Dimension of Dreams.
