What all do we know about cherubs as a species? I was wanting to make a guide on how to make fancherubs, but I almost forgot we don't know jackshit about them.

They are pretty much like the Universe’s Immune System Cells, a balancing act of Destruction and Protection. They’re coded to be polar opposites, with Evil and God alignments, although for a Fan Cherub you could switch this more to Chaotic and Lawful perhaps. They are born as a snake-y thing that has both personalities mixed together, but as they grow they start flipping from one to the next when going to sleep. Ultimately, one of the two has a stronger will and consumes the other, fully maturing. From then on, the Cherub will grow bigger, grow wings, and wander the infinite space of the Universe. They are said to feel the empty void left behind by the other Cherub they once shared a body with, and will spend their lives seeking out another Cherub with the same alignment to mate. At which point they become giant snakes, and the loser of their fight lays an egg. They’re said to have had a planet with a culture and civilization at one point, but as it is now, they seem more like a Force of Nature than a species.
