Kestralnamen was a male Orion who lived in the late 24th century.
In the 2370s, he was trade administrator for Bajor sector and claimed to be privy to all Orion transactions within it, though Benjamin Sisko considered him to little more than its head pirate. Sisko met with him on Mephil Trantos in 2372 to find out who had sold infected replicators to Bajor, though he lied about his knowledge and refused to answer.
Kestralnamen was quite a gourmand and quite overweight. He enjoyed Orion wing-slugs and nearly sold his information for a hot sauce that Sisko offered him. (DS9 novel: Wrath of the Prophets)
