Now it’s time for some norse mythology!

Depicted here is Yggdrasil, the world tree. It connected the different realms of the universe. Near the roots you see Mimer’s well (The source of wisdom, guarded by the head of the jotum Mimer) The three norns, who ruled over people’s fates, and the dragon Nidhögg that gnaws on Yggdrasil’s roots. At the crown of Yggdrasil, we see Thor, Frigg & Odin. (In the actual myths, Odin had two ravens, Hugin & Munin (Mind and memory) who survailed the world for him, but here, I think he’d send out his actual mind and memory, so to speak.

And, to explain the “fought their fates” thing: According to the norse myths, the fate of everything and everyone were predetermined, including most of the gods dying in Ragnarök. However, the gods still made futile attempts to prevent it.
