Eye of Anub-Ka
Recently unearthed outside of Nefra by Samira Ament and her team, the nonmagical object called the Eye of Anub-Ka is the egg of an eldritch creature. The opaque, light-green stone weighs 10 pounds and has abstract furrows on its surface.
The egg’s removal from its resting place rapidly accelerated the development of the creature inside it. Starting at 10:30 p.m., the egg’s stony shell becomes translucent, revealing the horror inside, and it begins to emit a pulse of magical energy every 10 minutes. Whenever a pulse occurs, each creature within 20 feet of the egg must make a DC 10 Wisdom saving throw, and a creature holding the egg has disadvantage on the roll. If the egg is placed in a bag of holding or some other portable extradimensional space, the effect radiates from the container instead. Any creature that fails the saving throw is subjected to an effect determined by rolling on the Eye of Anub-Ka Effects table. When a creature rolls for a new effect, the previous one ends. The effects end when the egg hatches or when the egg is encased in the crystal box Samira Ament provides.
