"Glory to Garendall!" -- the battlecry echoes off of the towering walls of Gidolan Keep. Screams of defiance, screams of death -- both pledge their allegiance and fealty to Garendall. The chaos and stench of a battle fought in desperation permeates the night air, thick with blood and fear.
Gidolan Keep lays under seige. Huge monsters, all tooth, claw, and muscle are assaulting the capitol city, threatening to crush the very heart of the kingdom in their malignant grasp.
Welcome to Pillars of Garendall, a huge (120 MB+) epic fantasy role playing game created using the Coldstone game engine. You'll need a sharp-edged blade and a heart of steel to make it through this unique action-oriented role playing game.
Both Macintosh and Windows users can explore Garendall's dream-like sprawling world and intricately woven tapestry of a story. Pillars of Garendall even has extensive support for plugins, which allow the game to be expanded far beyond the confines of its original design.
