Win lorin Ren was a male Tellarite trader in the mid 24th century, part of a trading network which reached across the entire Alpha Quadrant. From the 2350s through the 2370s, he worked in a sector of Federation space near the Talarian and Cardassian borders, dealing primarily in spices and foodstuffs. Alpha-currant nectar was one of his most popular items.

He was eventually cleared of suspicion. (CoE eBook: Troubleshooting)
