The lesser of Nirn's two moons, Secunda is acknowledged as one of the attendant spirits of the mortal plane, and, as such, is both temporal and subject to the bounds of mortality. Secunda, which exists as a separate plane, has long since perished; it was Secunda's death which led mortals to perceive it as having both texture and limited size, as well as imperfections of color, all of which are the results of its decay from its former investiture of pure white.
While regarded by various cultures as an attendant spirit of their god planet, minor god, or foreign god, Secunda is not displayed within Dwemer orreries, neither does it hold a position within the pantheon of Imperial gods.
Secunda received its title from the Aldmer, who knew the plane as Jone ("Little Moon God" in Ehlnofex). Similarly, Secunda finds itself invested with a position of authority and reverence among the Khajiiti pantheon, as its phase at the time of their birth - along with that of Masser, the greater of Nirn's moons - determines their form.
The Lunar Lorkhan suggests that Secunda originated as one of the halves of Lorkhan's "flesh-divinity", cast within the bounds of Nirn at the time of his destruction, and thus, is a personification of the dichotomy that Lorkhan legends often rail against: ideas of good versus evil, being versus nothingness, and so on. It is believed that Secunda was thus purposefully set in the night sky as Lorkhan's constant reminder to his mortal issue of their duty.
- Just like Masser might be based on pictures of Mars, Secunda might be based on pictures of Triton, Neptune's largest moon.
