Due to the events of Genshin Impact's 4.2 Archon Quest, the tags Furina (Genshin Impact) and Focalors (Genshin Impact) need to be split, rather than the latter being aliased to the former. This is due to Furina being a human created by Focalors to act as an impostor deity as part of the latter's plan to save the people of Fontaine from being wiped out by the prophecy.
Obviously, the tag of Focalors (Genshin Impact) would be for a spoiler character, much like how Makoto (Genshin Impact) is one.
