Ninthrill Forest

Ninthrill Forest is a large deciduous forest located on the southwestern reaches of the Central Continent, making up much of the western border of the nation of Parlera. A great deal of the forest exists on a peninsula that forms the Bay of Gulls, and partially forms the Bay of Bai’el. The northernmost tip of Ninthrill Forest reaches out towards the island of Erris.
Ninthrill Forest is named after the large, extraplanar insectoid creatures known as Ninthrill. The reason for their existing in the forest is unknown. Some rumors claim that they were summoned accidentally by Elven magicians, who lost control of the creatures, while others claim that the creatures came on their own, as some advanced scouting group seeking to colonize that part of Okarth. Less noteworthy creatures live in the forest as well, native to deciduous forests.
Ninthrill Forest is inhabited by many Wood Elves as well, who live in secretive, hidden settlements. Over the course of the past few centuries, Ninthrill Forest has been the spark that has brought Elves and Humans to war with each other more than once. Though the forest is claimed by the government of Parlera as her sovereign territory, this claim mainly extends to the outer edges of the forest- the many Elven settlements deep within the forest are completely unknown to the Parleran government, and such settlements do not accept Parleran sovereignty over them.
