 Every adult in the herd carries a herdstone, and to join the herd foals must independently travel to the Dancing Canyons and extract a herdstone of their own from the rock.Centaurs can use these herdstones to bend light around themselves, rendering the herd invisible from the outside, and they used this ability to hide their existence from humans until the events of Crystal Mask.Centaurs have developed powerful kicks for hunting and defence which make them very dangerous to attack.
