The Knowledge Pool is a torus-shaped pool of thought-inducing serum that floats above the blue lacuna deep inside Lumengrid. Vedalken study at the Knowledge Pool.
To look into its light is to meet the gaze of history.
During the events leading to the subjugation of Mirrodin to the Phyrexians, the knowledge pool became tainted. The one secret the vedalken did not reveal, even during the turmoil caused by the fall of the Synod, was the secret of the Knowledge Pool's destabilization. Some vedalken sages (Memnitect Sanctive) surmised that the pool had gained a quasi-sentience, and once partially formed, quickly went insane. This failure of the most sacred of vedalken banks of knowledge is kept as their greatest secret.
