The interesting lore developing behind the Blood Moon skins
The New Blood Moon skins are out, but with the text they put with them, an interesting lore is starting to develop, intentionally or not.
First, we saw Shen and Akali, telling the story of a girl being chased by a demon. Akali isn't super important in this story. The one that matters is the Shen, the demon.
Skip forward a few years and we get Blood Moon Kalista. Yes, this is how Ionia sees her, but lets take a look at what Shen was: A demon. Kalista is the first Blood moon demon to appear. This will have big implications.
Blood moon thresh, zilean, and Elise were the next ones to release. Thresh and Zilean are two more examples of Blood Moon Demons beginning to appear. Elise, on the other hand, is likely our first look at a cultist priestess. Only a few characters have been shown not wearing the mask over their full face in the blood moon line: Akali, Elise, and most recently Diana (only in her recall). This indicates that the cult is beginning to move, though it isn't doing much yet.
Then, the next year, two more beings appear: Yasuo and Kennen. Yasuo is probably a priest, as he is shown making the sigil on the ground, which only blood moon humans have been seen to do. Kennen, given how they released at the same time and appear to be linked in their release text, is probably a guardian demon to yasuo.
Then this year, the Blood moon cult finally made its move, and high-ranking members and powerful demons are appearing. The calligrapher, Jhin, is probably a priest. His methods imply that, given Yasuo, priests tend to have heavy links to the spirit world, and oftnen have visually impressive weapons, whether it be a katana or a rifle. Diana, on the other hand, appears to be an assassin priestess for the order, and dresses like someone who would take a life for the cult. Twisted Fate appears. He's literally a southern devil, and is shown to use trickery, though it is possible that he too is a human. Perhaps a human who was taken over by the blood moon? And finally, we have Talon. He's clearly only got killing on the mind, and is apparently the result of the asymmetry between the earth and the heavens.
So the Cult is on the move, while demons walk the land. That's the blood moon lore so far, at least the way I see it.
