Tauvid Rem was an Idanian operative involved in the undercover operation against Draim of the Orion Syndicate.
In 2373 he arrived on Deep Space 9 in order to meet Arissa. However, shortly before the intended meeting – minutes after 18:21, station time – he was assaulted and then vaporized by two of Draim's thugs. (DS9: "A Simple Investigation")
"Tauvid Rem" was probably not the operative's real name.
Tauvid Rem was portrayed by Brant Cotton and was credited as "Idanian" in the end credits.
