The Eye Is Opening. Thousands of years ago, living gods named Khepri wielded powers beyond understanding. Their bizarre magics rived a rent in reality itself. This portal—the Oculus—led to the deepest realms of Chthonic Darkness, but it was not yet fully open. Malign forces, opposed to all life, infested the Oculus, and waited. The Khepri kept vigil over the Oculus till time moved her hand. When the Khepri vanished in the Day Without Night, their Elven epigones took up the watch. In time, the Elves were conquered by the diabolic Thrassian race, and they in turn were subjugated by the Zaharans. Through the millennia, the caretakers of the Oculus studied, waited, and watched. Now the Awakening is near, the Spheres are coming into alignment, and the Oculus is beginning to open. The dark power is reaching out and for the first time in an age the Eyrie of the Dread Eye is accessible again. As the Eye opens, reality itself comes under further and further strain. And as rumors of a new valley containing an underground forgotten city filled with untold riches spread out from the Dark Wall, the Oculus continues to open ever wider. Eyrie of the Dread Eye is a ready-to-play adventure scenario presented for use with the Fifth Edition of the world's most popular d20-based fantasy role-playing game. Discover the vast ruined eyrie of the Oculus and take a stand against the coming Awakening. - from the publisher's blurb
