What is "edonia"

Edonia was an ancient region in ancient Thrace, present-day Greece, located to the east of Chalkidice, between the Nestus and Strymon rivers, in what is now East Macedonia and Thrace. It was home to the Edonian people, a Thracian tribe. Notable Edonian cities include Drabescus and Myrcinus. Later, the Greeks settled in the region, drove out the Edonians and built several colonies, including Amphipolis, and Eion. According to the Greek mythology, the Edonians were ruled at one time by Lycurgus who was destroyed by Bacchus for opposing his worship. The Edonides, the women of the Edoni and worshippers of Bacchus, murdered Orpheus, and were turned into oak trees.

"the pliant roots held her, and checked her, struggling. When she looked for where her toenails, toes and feet were, she saw the wood spreading over the curve of her leg, and, trying to strike her thighs with grieving hands, she beat on oak: her breasts turned to oak: her shoulders were oak. You would have thought the jointed arms were real branches, and your thought would not have been wrong." Bk XI:67-84 The transformation of the Maenads
