Kebren was one of the 3,000 Potamoi (River-Gods). His domain was a river that flowed through Troad in northwest Mysia in Anatolia. Kebren's domain was not overly large, his river was one of three of the tributaries which flowed into the much larger Skamandros which flowed around the plain of Troy. The other tributaries were the Simoeis and the Heptaporos
"When Alexander, Priam’s son, was tending his flocks on Mount Ida, he fell in love with Oenone the daughter of Cebren: and the story is that she was possessed by some divinity and foretold the future, and generally obtained great renown for her understanding and wisdom. Alexander took her away from her father to Ida, where his pasturage was, and lived with her there as his wife, and he was so much in love with her that he would swear to her that he would never desert her, but would rather advance her to the greatest honour. She however said that she could tell that for the moment indeed he was wholly in love with her, but that the time would come when he would cross over to Europe, and would there, by his infatuation for a foreign woman, bring the horrors of war upon his kindred. She also foretold that he must be wounded in the war, and that there would be nobody else, except herself, who would be able to cure him: but he used always to stop her, every time that she made mention of these matters. Time went on, and Alexander took Helen to wife: Oenone took his conduct exceedingly ill, and returned to Cebren, the author of her days: then, when the war came on, Alexander was badly wounded by an arrow from the bow of Philoctetes. He then remembered Oenone’s words, how he could be cured by her alone, and he sent a messenger to her to ask her to hasten to him and heal him, and to forget all the past, on the ground that is had all happened through the will of the gods. She returned him a haughty answer, telling him he had better go to Helen and ask her; but all the same she started off as fast as she might to the place where she had been told he was lying sick. However, the messenger reached Alexander first, and told him Oenone’s reply, and upon this he gave up all hope and breathed his last: and Oenone, when she arrived and found him lying on the ground already dead, raised a great cry and, after long and bitter mourning, put an end to herself."
