Ferrin's shield bashed into the lock...or at least, so Ferrin thought at first. But then he realized that some sort of blue barrier had appeared in front of it, causing his eyes to widen a bit. "Whoa.... That's...new." he murmured, quickly realizing that he wasn't going to be making any progress in attempting to brute force the lock. He didn't like it, but he knew he was gonna have to give up on breaking anything up here. He sighed and climbed back down the ladder. Once he was back at the bottom, he stepped through the flames again, and slid the shield onto his back. "So much for that. Apparently there's some kind of barrier stopping me from just breaking the thing down. Whatever kind of puzzle is in here, we're not getting around it."
