He spent the night talking with the centaurs, and pointed out that they HAD come further than they should, he had been having a spell going that made them travel faster than they normally could, having covered several days worth of journeying in one. He pulled out a local map, and showed them where they had been, where he THOUGHT they were, and where they were going, a lovely valley with only three ways in and out, with enough wilderness to support a tribe much larger than they previously had had. As for what would happen, he told them that his best information was the valley was unoccupied, though he didn't know how old the information was, so they might be sharing the valley with other settlers.
