Azura's Star (also called the Twilight Star) is a Daedric artifact created by the Daedric Prince Azura, and is prominently used as her symbol. In appearance it looks like a large, intricately designed throwing star or gemstone, with eight star-like prongs. In the right hands, Azura's Star acts as a reusable soul gem of almost unlimited capacity. It is considered to possess legendary magical powers. This makes it highly sought by mages and assassins. It can only capture white souls, but was once corrupted by mortals to trap black souls instead, becoming the Black Star.

Scholars who have studied the Star at close quarters, which is to say the very few who have been granted access to it in any of the ages in which it has been known to reside on Nirn, report that its internal structure bears no resemblance to that of any ordinary soul gem. What they describe instead is a facet of Moonshadow itself, Azura's own realm of Oblivion, inlaid into the material of Nirn and made portable. The Star is, on this reading, not an object Azura made but a piece of her realm she gave away.

It was created in the Daedric Era and by many this act is considered as the catalyst that lead to the foundation of the First Tribunal. Rumor places the gem deep within the hoard of the dragon Glaurund, coiled somewhere near the peak of Mount Druadac.
