Reidane, the god of justice, is youthful, arrogant, fanatical, and fully committed to the cause of justice.
Halvar, the god of battle, is selfless, stalwart, unwavering, and always the most sensible person in any room.
I think this is an interesting twist of expectations that also fits Tyr's association as a god of war but a noble and just one.
Cosima, the god of the sea, is intensely curious and tempestuous. Born a Cosmos monster, she can't stand being in one place for too long.
Insert Cosi/Kozilek conspiracy theory. Her being originally a Cosmos monster may refer to Skadi, who joined the pantheon of gods although she was a jotunn.
The Cosmos Elixir harkens back to the apples of youth and how the gods started aging when they were stolen. Before they defeated the elves and started drinking the Cosmos Elixir, I wonder if the Skoti were human.
They vary in size from the unimaginably massive Cosmos Serpent to the tiny, mischievous squirrel Toski, who is small enough to sit in the palm of Esika's hand.
Didn't the first story with Kaya refer to Toski as a giant squirrel?
If the Kannah leave the forest, winter follows them and torments them with constant, increasing snowfall, eventually making forward progress impossible and forcing them to turn back. The Kannah maintain a small settlement near the Cursed Tree, where they perform runic rituals in hopes that one day the curse will be lifted.
This is cool for the green Humans, and them being the most god-hating.
