If you thought a stroll was all it would take to get away from the end of the world, sadly, you were mistaken. None are meant to escape this inevitable end, and the continent seems to resent you thinking you could forget, even for a moment, the weight of its hatred for wolvenkind.
If its boredom you seek to alleviate, that can certainly be arranged!
The distant mountain shakes, and from a thinning place in the forest, you see another horrific gash of blue open up to swallow that hazy scenery. It's... far enough away. You're probably safe.
Or you would be, except that the jostling sets free eroded stone faces. Now a horde of tree-shattering, multi-ton rocks are rolling at increasingly alarming speed downhill in a cloud of smoke. Towards you. And, like a last laugh from the universe, one of those burdensome boulders is glistening with a rune.
If you can avoid getting flattened, and keep track of where it lands down here in the valley... you can probably retrieve it.
The resolution of this event is entirely up to you. Your success retrieving the rune is assumed with no further Narrator intervention needed. Note that you will perish if you fall into the crack!
