The most mysterious region by far, Elves of all varieties settled it while Cradle was in its infancy, tales from Althum say its a land covered in large crystals, and all expeditions into the unclaimed territory between Althum and Essilada have resulted in tragedy or total disappearance, there are many stories of how Essilada operates but the only one confirmed is that they worship Valasi the Indomitable Mother.
The area under Essilada’s control is snowy year-round and all standard rock formations are replaced by crystals of blue and purple hue. The Windswindler's Strait acts as a major border between it and both Il-Oovi and Althum, with Althum’s navy being the only reason anyone has any real contact with Essilada. To the south, the unclaimed territories act as a functional land border between Essilada and Althum as neither makes much progress going into it (that is seen). Essilada’s eastern shores are covered in these crystals that mostly protect it from pirate attacks coming in from the islands in the Sea of Tears. The north and far west of Essilada is the Oov-Rasha, where not even the Althumn Navy ventures.
