Hallbjörn shrugged as he was questioned, on how he would repay the bird halfling. He didn't know the answer, but he pushed his great axe forward a bit to present it. Moments later he pulled back close to him, "I will pay with my blade. Just the same as I do, for man I crush." He explained simply, yet proudly. He purposefully took the time, to flex his arms, showing off his primary talent. Which was, unmatched strength.
"Please, this a cave. Let me fight for you. This is a dangerous place, whole town say so. I will let you take whatever we find." Hallbjörn made his final, and defining offer. As he stood with his axe in hand, a slight grin on his face. He seemed more than formidable as a warrior, and his posture showed that he was not one to ever give in, or break a promise. He was a fighter, a stupid, and easily manipulated one. But still a fighter. It was just good luck, he had fallen on these two, rather than something else in the cave.
