Description from the back cover:

A hidden key unlocks ancient castle's door. As it creaks open on rusted hinges, the whisper of a dank, stale wind delivers this chilling warning: Danger awaits you. Yet within these dark and ominous walls lies your quest.
Welcome to the Castle Shadewgate.
Your destiny, as the last of a great line of hero-kings, is to terminate the diabolical Warlock Lord before his dreaded black magic unleashes the hideous Behemoth and destroys the world.
With a strong heart and shining armor, you carefully choose your path of travel throughout the castle's sinister grounds. Along the way, you'll discover strange and wondrous objects. Some things may be useful on your journey. Others may be deadly to the touch.
Three-dimensional images, unsurpassed graphics and special sound effects unfold as you venture through those grave ruins. But beware!
Your next move could be your last.
Using screens and graphics like those in the best interactive PC games, Shadowgate is the most challenging, participatory adventure you've ever experienced on the Nintendo Entertainment system!
Shadowgate. Enter if you dare.
