Rivers in your mouth

The sound of crunching and of wings fluttering, like a dozen birds taking off at one, brought her attention to the nearby structure. It looked like it was made out of stone, with some strange sort of see-through substance broken off in sharp, protruding bits around and opening in the stone. She’d never seen anything like it and it peaked her interest, getting her to her paws. She gave her coat a swift shake, spraying water all around from her head to the tip of her tail before she began to make her way toward the structure. But, she paused.

A pair of silver eyes stared back at her.

For a moment she thought it was Scully, but as the figure stepped further into the light she could see that it definitely was not. They were huge, bigger than her. Something other than a bear or large prey was bigger than her for the first time in her life and she felt herself tense up everywhere. They looked like a wolf in figure, but as more light peeked through she could see two sets of horns protruding from the beings skull.

“Who and what the hell are you?” she said, partially to herself and partially to the...wolf? In front of her. The sound of the fluttering grew louder from within and she looked past them for a moment, brows drawing together in confusion. Was that sound their doing too? What kind of hellscape had they come to where wolves were bigger than her and had horns coming out of their hecking heads?
