Hellblade: Senua's Sacrifice (№ 299405)

The northerners say that the rainbow we see is actually the bridge between the human world and the world of the gods. Yet, they say, the frost giants and mountain giants are unable to ascend to it, but when it comes Ragnarok, nothing in this world will be saved. Rainbow bridge collapses, when it will be the army of fire giants on the flaming horses.
