Kaylar

The Kaylar are a primitive warrior race native to Rigel II. They are similar to Humans, except they are bigger in size on average. When first encountered by the Federation in 2254, they still used spears, swords, and rudimentary armor. For centuries, the Kaylar had defeated every attempt by other species to colonize their planet. It wasn't until the Rigellians settled in the late 23rd Century that they allowed an association to form. Most still cling to their traditional ways and technologies.
