Porcupine Ridge immortals

Lucky for Ruenna, it was too early in Thorin's story for him to roll an ankle — his player isn't that cruel.  He chalked it up to good luck, since he doesn't know anything about this fourth wall.  He's assured when she comes into view; he visibly releases a breath he didn't realize he'd been holding, then chuckles good-naturedly at the realization.  Why, thank you, he says as he reaches the path, Don't think I could've done it without you.  What're you doin' all the way up here this morning?  Now that he was close he thought he could smell pack on her, but he hadn't come close enough to the Plateau to scent its borders and hadn't come close enough to the Wall to look down upon them.  You from 'round here?
