Kaldheim

The planeswalker Kaya visits a world of prophecy and legend, mortals and monsters. A world of many realms, epic sagas, bound by one truth. Viking or Valkyrie, Elf or Dwarf, all belong to the World Tree, all are supplicant to the gods. Gods who travel between the realms to do their bidding for peace, for bloodshed, or for their own amusement. But what if there was a way to harness this power? A weapon with the ability to protect all. A weapon of pure strength. Forged for a god. Or... in more creative hands, a weapon of unimaginable chaos. The World Tree is the origin of all life on Kaldheim, and you can see the branches in the sky in all ten realms. However, they look different in each realm. The Ten Realms are constantly shifting and moving around the World Tree and can even collide. Such an epic event is called a "doomskar" and causes earthquakes, destabilization, and total chaos.
