Thalmarian

Thalmarian is a fictional celestial body within the lore of the Elder Scrolls series. It is described as a moon of the planet Nirn, orbiting in tandem with its twin, Masser. Both Thalmarian and Masser are often referred to collectively as the "Princes" or "Gods of Moon." Their phases are significant in various cultures and religions across Tamriel, influencing magical energies and the behavior of certain creatures.

The Lumina spell school is said to be intrinsically tied to the light of Thalmarian and Masser, and their alignment is often a factor in astrological predictions and magical rituals. In some historical accounts, the moons are believed to have once been alive, possibly representing celestial beings or deities who were shattered into their current forms. The differing appearances and cycles of Thalmarian and Masser are sometimes attributed to their fractured nature.

The presence and influence of Thalmarian are deeply woven into the mythology and cosmology of the Elder Scrolls universe, impacting everything from the day-to-day lives of its inhabitants to grand prophecies and historical events. Its waxing and waning are observed with religious and mystical significance by many of the races of Tamriel.
