From publisher blurb:
The third level of the Halls of the Eternal Moment are the domain of Illquis of the Thousand Eyes. Illquis is a derro necromancer, and was once a figure of great power and an ally of the wizard that laid claim to the Black Star. She has been trapped deep within the Halls for the last age, finally freed as the unleashed power of the Star that froze time in this place slowly began to unravel. Illquis is only a shadow of her former self, quite literally. The strange temporal warping of the Halls has displaced her in both mind body.
Infinite Dungeon: The Halls of the Eternal Moment Level Three - The Clairvoyant Hall is a great add-on for the Infinite Dungeon mega dungeon. This level is perfect for 3rd level adventures and promises action and excitement.
