Was Runaan a Darkin?

"Vaarus"

No, just no.

Nnnno. There aren't 2 bow Darkin. The next Dakin is going to be a broken scale, and is going to be connected with "The Great Balance" in the lore, and is most likely held by the golden armored warrior queen and her sister. The 5th Darkin is most likely going to be based on the myth of the Baba Yaga, a weird witch with a walking house, that flies in a mortar and wields a pestle, and who, for some reason, has the horsemen of the apocalypse just walking around her forest.

Inb4 Runaan was chosen to be Varus Darkin bow before the retLGBTQcon.

Riot has already stated that Darkin don't have a universal "aa" name schtick. Aatrox, Rhaast, Varus. Those are the names and how they're spelled. If they really were going to cement the "aa" thing, they would have changed Varus' name to "Vaarus" when they did his lore update. But they didn't. So it's Varus.

Does this mean we're making Kindred a Darkin now? Lol

It has two A in the name so it checkes out. Aatrox basically confirmed in his new quotes that two A are common in Darkin names.
