Largest of the five forests in the kingdom of Cyrendar. The Thistlewood is the largest wooded region in the realm of Cyrendar, and is a dark and mysterious place, where few men dwell except for rangers and druids. Deep inside the wood are rumored to be many ancient elvish ruins from the realm of Ectharë, but most are now covered with the overgrowth of nearly 3,000 years. Also, a large population of Wood-Elves reside here, although they mostly keep to themselves and shun outsiders.

The woods are named for the many thorn bushes and sharp undergrowth found there. Traveling through these woods can be quite difficult and treacherous. Deep within this forest is Tall Tree Keep.
