Hideaway Strath BWP: time makes you bolder

Happy Landslide Day! The passage connecting the Strath to the outside world is now closed until further notice. Anyone on either side of the passage feel free to respond! I'll jump in with Rue once a few people get responses up.

It was midmorning when the subterranean beast finally stirred from its slumber, and the earth churned with the creature as it rolled and shifted and stretched. The above-ground inhabitants of the Strath would feel the rippling effects of its agitated movements as a dull, ominous rumbling that had grown all too commonplace in the last moon or so. 

The beast thrashed in annoyance. The burrow had always been somewhat cramped, but lately it had become too constricting and dark, and the air was stale enough to choke upon. The more the beast moved, the tighter the ground squeezed, and the creature was reduced to wild flailing and bucking. The surface roiled, and the rumbling turned to a deep, guttural roar.  

The beast arched its mountainous spine, and the Strath heaved in response. Boulders and debris rained down from the peak in waves, gathering enough force in the tumble to beat down all but the mightiest of trees and bury anything which remained. Finally satisfied, the underground monster settled, and an eerie silence stretched out over the transformed landscape.
