Tirilazad

Tirilazad is a term primarily found within the fictional universe of the Forgotten Realms, a campaign setting for the Dungeons & Dragons role-playing game. It refers to a powerful magical item, specifically a Gatekeeper Crystal.

Gatekeeper Crystals, including Tirilazad, are remnants of a much larger, and now destroyed, structure or artifact known as the Gatekeeper. These crystals possess potent magical properties, particularly in the areas of divination, warding, and protection against planar travel and influence.

Tirilazad is known for its ability to both detect and block extraplanar entities and portals. Its specific powers and limitations vary depending on the edition of Dungeons & Dragons and the specific campaign setting within the Forgotten Realms where it appears. It is often sought after by both good and evil forces due to its strategic value in controlling access to different planes of existence. The crystal's use might require specific attunement or knowledge to unlock its full potential, and misuse could lead to unintended and dangerous consequences. It is often described as possessing a visual characteristic, such as a specific color or internal pattern, though these details are not consistently defined across all appearances.

The history of Tirilazad, like that of the other Gatekeeper Crystals, is often shrouded in mystery and connected to ancient civilizations or powerful mages of the past.
