Soooo that DLC announcement huh? Pretty cool. Very excited but oh my god that promotional image has so many implications.
Mainly, if that person riding torrent is in fact Miquella, which seems to be the running theory at the moment then it suggests that Miquella himself was very likely torrent's former master, which in turn implies a lot about certain character relations we didn’t know about until now.
The big one being that on top of Malenia, he was possibly also working closely with Melina and Ranni as well considering the two of them both have ties to torrents former master. Melina travelling with his old steed and Ranni being tasked with finding the steed’s new master and giving them the spirit calling bell.
It makes sense for Melina since she’s very very likely the secret, missing third child of Marika and Radagon, which could be a post all on its own, so her working with her two siblings isn’t that strange. (though I still wonder to what extent they’re related and possibly working together).
But the craziest thing to me is that this also implies that not only could Miquella and Ranni have been on good terms at some point in the past but also that they are still currently on good terms (even after what she did in the night of the black knives). At least good enough terms to trust her with the spirit calling bell.
Melina's possible connections to the black knives also makes this theory even stronger. If she was a part of the assassin squad then that means that Ranni stole the rune and Melina would have been one of the assassins that used it to kill Godwyn (and possibly other Demigods since he was only said to be the first to fall during that night).
Hell if you wanna get real crazy we could say that Miquella helped to forge the black knife weapons, since he’d already done a lot of research into “anti god tools” with stuff like the golden needles. Who’s to say he couldn’t figure out a way to do it? But why would he do that? He’s about the only demigod who wouldn’t be ok with killing Godwyn but it’d explain why he was still on good terms with Ranni after the assassination. Could have been St. Trina for all I know.
