Cormanthor
In the 1200s DR, a plague affected the numerous centaurs in the Cormanthor forest, causing their left hind leg to be three inches (7.5cm) shorter than the others, and as a result, they could not easily escape from predators such as dragons. The elves and halflings of the forest refused to help, fearing that the dragons would turn on them too.
Today, only three tribes of centaurs remain in the forest, each containing around one dozen families, and they are nomadic (within the forest boundary). Their migrations follow the same route each year, spending the winter in the east starwood. In the early spring, they move west, around Myth Drannor, and south to the Semberholme area, where they spend the summer near Lake Sember. At the end of the summer they travel east, stopping for the autumn in the central starwood, before repeating the cycle.
Although the centaurs follow the same trails they have created over the years, these can be difficult for others to follow because they have been disguised with a hallucinatory terrain spell created by the centaur leaders' magical amulets. These amulets were donated by an unknown friendly human priest.
A typical centaur.
The centaurs of the Cormanthor forest are not as friendly towards other creatures as their counterparts elsewhere. They use falcons as scouts to warn them of nearby creatures, and are likely to attack on sight, with their bows. They are still respectful of their surroundings, and will protect the forest and its wildlife. They are known to enjoy pears and peaches in particular.
