Jaglom Shrek

From Memory Alpha, the free Star Trek reference.

Jaglom Shrek was a Yridian information dealer.

In 2369, Shrek traveled to Deep Space 9 and sold information on the fate of Mogh to Starfleet Lieutenant Worf, son of Mogh. Shrek claimed that Mogh was still alive 25 years after the Khitomer Massacre, and transported Worf to a Romulan prison camp in the Carraya sector in his shuttlecraft. However, Mogh was not among the survivors in the prison camp. (TNG: "Birthright, Part I", "Birthright, Part II")

Shrek was played by actor James Cromwell.
