Melodia is Sagi and Milly's daughterAnd because of his loneliness, Calbren adopted her, or one or both of her parents, as his heir to the Duchy of Mira.
The baby at the end of Origins is KalasSince in a side mission in the desert, you can find Georg and he gives you a blue container for what basically amounts as naturally wasted magna essence (mana, if you will) from experiencing emotions, you can conclude that he was gathering human feelings to make a fake human, Kalas, who can be seen floating in a blue void at the end of Origins as a recently formed baby. In other words, the baby is not Melodia, as some parts of the fanon say.
Mizuti and Kee's parents agreed on an Arranged Marriage, as per Duhr traditionsIn Origins, you can see Kai preparing her part of the communal house for when her new neighbors, namely Koh and his parents, move in. Then, in EWLO, you have Mizuti living in the same communal house as Kee. It's vaguely there, but it seems to be a Duhr custom to marry off a girl to a boy by having him move right next to her living place in the communal house.
Corellia is, indeed, a fairyIt has become a meme that Corellia is immortal, and has been around since the age of the dinosaurs or even earlier, but no one seems to care about why she'd be so, so let's point at her title in Anuenue, the Fairy Guide, and at her insanely close ties to the Celestial Tree, including the sheer skins she left behind at the roots in Origins, to point her out as a potential member of The Fair Folk (albeit most possibly as a dryad than as a fairy)
Xelha gave up her crown at the end of EWLOIt's pretty evident she elopes with Kalas to the Celestial Alps, which leaves open the mystery of what will happen to Wazn now...
The real Lord of Sadal Suud is Palolo IBut Rodolfo is a dick, and he'll keep his descendants on the streets.
When Peachy says Melodia is the true heir of Mira...Melodia was having her first period, hence the blood; she was not raped. This comes from the fact that Melodia is basically a zombie until rescued from her fusion with Malpercio, so her period would signify she was alive and well. At least, superficially...
Cebalrai is fuckedSalt rain on farmland? No way that's going to end well. This will show up as a plot point in a third game.
Kalas's spirit is the same as Sagi'sGiven the first WMG and how Melodia is present in the "summoning", which the GS came to Kalas. The spirit doesn't remember Origins because the memory loss spell works on Exact Words, erasing their memory of the world before it was cast. How it works when Sagi's GS is really part of Malpercio I haven't figured out yet.
The ruins of Tarazed will be visited in a third gameI'd say Scavenger Town.
