"Very kind of you." Rhys smiles, though it gets a bit strained when she mentions looking for her sister.

"You were with a satyr? And your sister's missing?" He has a similar story, except for the satyr part. He found his way to the quest that was out of the camp at the time, but he didn't have any help but the birds. "He might have been spooked by the wolves. Goats and wolves, not great friends- but come on, we should get you inside."

If she is a demigod, or one of the other options, the Barrier should have no problem letting her in. If not... well, it wouldn't. Right? That was how it worked, as far as he knew.
