From publisher blurb:

In The Heart of the Forest, Adventure Awaits!

This companion book to Green Ronin's Bow & Blade fully details a wood elf village designed to fit easily in any fantasy campaign setting. The remote tree-top village makes an excellent home base for a wilderness-oriented campaign, or an exotic place for existing characters to visit. The current political and religious crisis offers a starting point for play, while the many adventure seeds and plot hooks ensure that Corwyl will remain interesting for the life of the campaign. Corwyl: Village of the Wood Elves also includes:

• A complete history of the village, including details on the Dark War with the drow fortress of Dezzavold.
• Over 40 fully detailed NPCs.
• Two new core classes (Ancestral Speaker and Terellian Knight) and two prestige classes (Animal Master and Tree Maiden) tied to the village's background.
• A plethora of new feats and spells, complemented by choice additions from a variety of open sources.
• A handy "Who's Who" appendix to make the GM's job easier.
