The Sand Warriors

The Sand Warriors are a clan of Dorne's desert.

History
Once a small group,they took advantage of the great civil war and seized many wells. However, Darrack, their leader, died during a battle, leaving behind only his 4 years old daughter Nymeria and his wife Elarya, who became their new leader. The lord of Yronwood, fearing their power, started negotiations with them, which ended one year later with the marriage of Elarya and Edric Suxen, heir of Yronwood. Ever since that day, the Sand Warriors are loyal allies of Yronwood.

Culture
The Sand Warriors are a clan of fighters, and everyone must always be prepared for battle. For this reason, every child, when they become 3, begin their training with a small curved knife, a weapon that shall not leave them until their coming of age ceremony, at 16, when they are given a scimitar which they are to use to kill and skin a jackal that was captured especially for the event. Some people think that it is a representation of an old victory against a long deceased house. Of course, knife and scimitar aren't their sole weapon, as they are trained to use lances.

Sand Warriors have a custom to offer children clothing, and to put them by themselves. Apparently one of their superstition is that if someone not from their clan put one of their dress without help from them, the spirit of one of their fallen warrior come to haunt them.
