Blafu

From FrathWiki

The Blafu have traditionally been the dominant culture of the eastern part of Odirá. For much of Odiran history, the Blafu were the technologically dominant culture. Today, most Odiran languages (and many non-Odiran, as well) borrow from Classical Blafu for scientific terminology.

The Blafu religion was based upon the worship of the Silent God, the god of death. Their religion considered deafness sacred, and its priesthood used a sign language known as the Sacred Hand.
