Into the world came Seraphim, and very quickly they understood that they were not wanted, not by their pride, not by anyone. Different, that is what they are, winged and glowing, they could only think to call themself an angel. They know deep down that's not true. Another glowing lion was around every so often as they grew up, and that lion called herself "Fae". Whatever that is...
Seraphim grew soon too big for their pride, and decided to leave. For days, weeks, months, they traveled, in search of territory to call their own, when they stumbled upon a firey winged lioness. Another winged lion was all Seraphim saw, but no matter how sweet they were to the lioness in flames, they could only draw snarls and grumbles out of her. Despite this, the flaming lioness never told Seraphim to leave, so they decided they would not, the the grumbling and complaining of their new companion, Seraphim would sit firm by their side for the next few months. Until this grumbly lioness started warming up to them, slowly, they were allowed to sleep first with the lioness's,
Prometheus, they learned was her name, pride, then, after nearly a year of staying, they were requested to join Prometheus in her own cave as she slept.
Seraphim could not stay though, no matter how it tore their heart to leave their new companion's side, they left with a portion of the pride, as a parting gift, and settled in the neighboring territory, establishing the pride they had dreamt of.
