I mean, we're going to Gravesfield next turn. My hope is that we arrive in time for the events of Yesterday's Lie.
Wait for it to turn out the Gravesfield name drop means nothing and the Owl House doesn't come up at all. Which seems likely because, remember, the show isn't actually over yet.
(Which, granted, doesn't mean Occult stuff won't come up, but still.)
Lab_Accident, I would love to recruit Janna 2: Basilisk Boogaloo, but in terms of possibility I'm leaning towards woweed's opinion there.
*(these possibilities are not actually by any means exhaustive)
After all, I
said this, and wouldn't you know it, I forgot to mention Possibility #3: Vee hasn't even come to Earth yet.
weredrago2 said that Amphibia (and possibly The Owl House) will be included at some point. Key word: at some point.
Amphibia is finished, but The Owl House isn't. The ostensible airdate of the beginning of S3 ranges from October to next March, depending on where you look. And I'm guessing that the GMs won't want to definitively add in any major TOH elements until they have a full understanding of (to quote weredrago2) "where it'd make sense for the bad guy to win and what might happen next."
Furthermore, there's the issue of in-universe time to consider.
(Yes, time in Disney cartoons is unclear at best even in canon, yes, as weredrago2 just said, "Time travel is weird", yes, as Felldrake said in the Xanadu quest, DoofQuest takes place along "a Gordian Knot's worth of paradoxes pretending to be a timeline", but there's still a
little bit to take into account from that angle, I think)
In-universe, we're finishing 2017 right now. The Owl House (2019-present), set vaguely in "the present", begins in.. well.. late teens to early twenties, in-universe.
But, at the very least, we can be reasonably sure that it began no earlier than summer 2017, because in Moolah and Magic (Halloween 2016), there was a cameo by someone who was probably Eda.
(Okay, this doesn't exclude the possibility that Belos won but Eda made it out of the Boiling Isles, but I think that's unlikely.)
And I say summer because the key inciting incident of The Owl House is Luz getting sent to summer camp, which presumably occurs in May or July. Season 2 (and thus Yesterday's Lie), judging by Vee having returned from summer camp, takes place during late summer or fall.
So I think we're either too late for Yesterday's Lie or much too early.
Buuut as I said, DVV is weird, for all we know Luz could have been sent off to winter camp instead, we don't know anything for certain.
