Each hides a mystery that's waiting to be solved, and together they just might hold the key to a secret of the multiverse. All a body's got to do is tumble to the right keys, open the doors, and face down the Unknown." - Estavan, merchant lord Doors to the Unknown is a collection of four Planescape adventures that can be played separately or as a mini-campaign.

It is filled with rich treasures both precious and magical, but in addition to the aforementioned guardians, there is said to be a demilich who still wards his final haunt (Be warned that tales told have it that this being possesses powers which make him nearly undefeatable). Accounts relate that it is quite unlikely that any adventurers will ever find the chamber where the demilich Acererak lingers, for the passages and rooms of the Tomb are fraught with terrible traps, poison gases, and magical protections.

To stop him, heroes must face horrors never dreamed of, journeying to a shadowed city where Death rules and the living cower. Here, Iuz will achieve his mad dream by destroying the imprisoned master of that alien citadel: Vecna, the mightiest lich, an immortal demigod. Two items exist with the power to stop Iuz—the Eye and the Hand of Vecna—but using them carries fantastic risks. Not even the gods know what will be unleashed when these items are fully activated.
