OOC
Bristle remembers that there is a cave to the northwest, Halson's Grotto. It's got a bad reputation, but then, the wilderness around these parts all has a bad reputation. Halson's is different, though, because it has a specific folktale surrounding it. Sometime around when Darkmoon Vale was settled, Sir Elias Halson was one of the major people in the settlement that later grew into Oregent. He was a paladin of Sarenrae, who fought the dark things in the woods on behalf of the settlers. He went to the cave that now bears his name in pursuit of...something, a demon they say but then villagers around here hardly know what the different types of fiend are. He slew it, so the story goes, but died in the doing, and left a warning to leave the cavern well alone.
How much of the story is accurate is hard to say, but it matches the direction and the appearance of the stone, so Bristle is fairly sure that's the place she dreamed of.
