:: Background Story ::
(Spoiler Alert)
Angelira is one of Luna's four guardians, who had appeared in her beast form to save Luna from the waterfall and drowning in the river after her mother's death. Carrying Luna to shore, Angelira turned back to her animal form in order to get Tyrin's attention. Once conscious, Luna kept her as an adored animal companion with Tyrin's consent.
It was on the night Luna turned 16 and was attacked by demons, that Luna's necklace reacted and enabled Angelira to reveal her anthro form to defend Luna and Tyrin. When with Luna and Tyrin, she stays in her anthro form - but turns back to her animal form when venturing to the city.
Later in the story, the guardians' origins are revealed: where they came from, how they came to be, and why they were created. However, until then - the guardians do not know anything themselves nor remember a past before meeting Luna. The only thing they hold onto is knowing deep in their hearts that that exist solely for Luna; her happiness and safety.
