There's a lot to unpack, so here's just a starter:
- Birgi, Toralf and Kolvori are children of Alrund and Cosima.
- Cosima was originally a dolphin
- Birgi hires dwarves to keep tabs on her brother and steal his credit
- Halvar was adopted
- Valki, while selfish, was originally just a prankster. Tibalt acting as him is actually malicious, which I think is a good nod to the disconnect between Loki in earlier parts of the Eddas and his role in Ragnarok.
I heard somewhere we won't see them all? Although all colors seem to have two, with Green and Black getting three. Wonder how Kiora would feel about this god, and how she'll be distinct from Thassa, who will always be my fave. <3
It'd be very strange if we didn't get the remaining three gods, especially given how Reidane was one of the earliest spoilers. As to how Cosima differs from Thassa, I imagine its the typical "Kaldheim gods are enlightened mortals, Theros gods are cosmic forces" way. Ironically Rán is more of an "elemental" figure than Poseidon.
