Hagar knew of the cavern system beneath the fields to the west, but he had not thought that the honeycombed ground would have extended to beneath their very feet. Chasing after a relatively plump badger, he had made the effort to dig out the stubborn creature's den and exposed the riddled limestone it delve into. It didn't take long for him to realize what he had discovered; the entrance to an underground cave, and within it, he smelled water.
Excited, he prowled about the opening, assessing and attempting to safely access the dark, dank space. When he did make it inside, he was able to find footing on moss-slicked stone and make out the pale shapes of eyeless fish swimming within a shallow, cool pool. Relief flooded him, and he scampered back to the sunlight before taking a even single drink for himself. Avella had to know.
He threw back his head and howled to the pack, I've found water! and food!
