Moons of Ionia is a series of alternate future/universe skins in League of Legends. Set in the mythos of Ionia, it features champions as Ionian demons or cult worshipers of the Blood Moon. A voice echoes from the silence: "Writhe, beasts, brethren. The moons of a doomed lonia rise like eyes of starved demons, awaiting the red of your fealty—or are they monstrous blights that cannot pass? Either way, we are vessels plunged in ritual and sacrifice. At the moon's peak, we carve flesh from flesh, offering the meager gift of all that we are."

This is a shared splash between Blood Moon Katarina and Blood Moon Master Yi.
