When Cait Sith speaks to Atomos, he asks him to stop devouring our future based on Altana's wishes. Atomos (or rather the Cavernous Maw in Walk of Echoes, it was never specifically said this was Atomos-- and it speaks of Atomos in the third person so..) states that no avatar nor god can stop him from doing what he was summoned to do. Cait Sith, obviously, is aghast that an avatar would rebel against a God. This is interesting to me because it actually comes out and states that both are avatars, presumably different from celestial/terrestial
Remember Flit from TOAU? He's the Shadow Lord's personal Herald instead of Luzaf's at this time. Considering both Luzaf and Raogrimm are Odin's Knights, I wonder when Flit jumped from Raogrimm -> Luzaf, as Luzaf has been dead for a long time before we arrive, centuries iirc.
Robel-Akbel did "fail" Lilith, and not Lilisette. Lilith and Lilisette are the same person. As in, Lilith is Lilisette from a different future.
It is not the Rage which Odin seeks from Portia and Ragelise, but their love. If I remember right, Lilith goes on a tirade about the emotions the Dark Divinity values most: Rage, rancor, envy and love. Lilith also explains in her timeline, the Shadow Lord rules over the entire world. (Actually I think Cait Sith is the one who does this)
Cait Sith and Lilith also reveal to us that Lilith's world is Universe 1 per se. That is, her world came first, and our's is Altana's idealized version. In Universe 1, Lilith's reality, there are few races of Altana left alive, but they keep fighting against the Beastmen. This is where I get confused, because in Universe 1, Ragelise makes the pact with Odin during the storm of Zvahl, right about when he rescues Portia. (In our reality, Universe 2, this is where he turns down Odin's offer, if I'm remembering my dialogue right.) So that makes the current WOTG timeline a sort of Universe 3? Also, being imbued with Odin's power allows Lilith to control demons too, which is interesting that in her world Odin's armies are fighting each other eternally. (Which makes sense! Look at the Norse concept of Einherjar, lol)
And then Rocl was a demon.
