Centaur

Centaurs have the upper bodies, down to the waist, of muscular humans, displaying all the human variety of skin tones and features. Their ears are slightly pointed, but their faces are wider and squarer than those of elves. Below the waist, they have the bodies of small horses, with a similar range of coloration — from various shades of chestnut or bay to dappled or even zebra-like striped patterns. Most centaurs style their hair and their tails in a similar way. The upper bodies of centaurs are comparable to human torsos in size, and their lower equine bodies average about 4 feet tall at the withers.  
"The following communities are known to the people of Myzelis and recorded in the Journals of Eblin. Realms not listed here have no known populations of these Aethrin large enough to list as communities in their own right."

Gylidder Centaurs

  The Gwassten Runners: Centaur communities are commonplace upon the Gwassten, where they congregate in herds of free-running families that gather beneath the colossal Clodd Trees. Their open demeanor is quite giving and forgiving, and their architecture - mainly huge, flowing cloth pavilions that can be seen for miles around - is entirely without solid walls, preferring instead to use space and dividing curtains for privacy. Each of the families that roam together send their eldest capable members to gatherings among their own kind, and some among those are granted the authority to represent the Gwassten Runners in the Gyliddring. One such leader is Gwendil Tora, a Centaur who channels the summer lightning and speaks with the voice of thunder.  

Verberan Centaurs

  Proud & Powerful: Verberan centaurs come from the Feywild where they live together in larger family groups. Many view them as the most similar to the natives of the island, as they share the fierce bonds of family & friendship that drive them to protect. The Guardian Grove in the Feywild hosts the largest congregation of centaurs in the Realm.
