An Yridian information dealer who sold Worf the claim that his father had survived Khitomer as a Romulan prisoner.
Jaglom Shrek is an Yridian who trades in secrets and rumors. He approaches Worf while the Enterprise is docked at Deep Space 9, offering news that Mogh did not die at Khitomer but is alive in a secret Romulan prison camp.
In Birthright, Worf at first rejects Shrek but finally pays for passage, and Shrek takes him to the hidden camp. Mogh is not there, yet Worf finds Klingons who were captured at Khitomer decades before. Shrek was played by James Cromwell.
