You took a look at the sign on the left as it explained where exactly what was on the end of that path, after you arrive at that specific location to see if it could lead you. The sign labeled the location as the centaur village, as you figured, that you might hope that they would either help you, trick you, or kick you out of their home.
You decided to take any chance you had, as you proceeded to where the sign for the centaur village was, and hoped that the people there would be kind enough to help you with saving the princess. Centaurs were fast, powerful, and energetic creatures that were half human, and half horse, while you hardly see any of them near the homelands of your kingdom. By the time you got closer to their village, you trip, and fall off a cliff, then roll, and get injured by a bunch of rocks in the path.
