Norse Mythology
We got lots happening here. The big dog up top is Fenrir the wolf who cant stop growing bigger. The World oak tree is there. Theres the chariot and the various hammers crows and the World serpant and more.

“Fenrir or Fenrisúlfr, also referred to as Hróðvitnir and Vánagandr, or Vanargand, is a wolf in Norse mythology. Fenrir, together with Hel and the World Serpent, is a child of Loki and giantess Angrboða.”

The Norse god Tyr was given the task to restrain Fenrir. In this struggle, Tyr lost an arm – his sword arm, to the wolf.
The day of the week Tuesday, is named after Norse god Tyr.
