Sons of Mogh

Worf, the only Klingon officer in Starfleet, receives a visit from his brother Kurn, seeking help to escape the dishonor that has befallen their family.

As a result of Worf's choices, his family has been stripped of its wealth, honor, and political power.

Worf and Kurn are sent on an undercover mission to discover the mines' locations and activation codes.

They are able to access the data, though Kurn is forced to shoot a Klingon officer in order to defend Worf.

Using this intelligence, Major Kira is able to detonate the mines and flush out the cloaked Klingon vessels.

Having killed a man who was acting in defense of the Klingon Empire deepens Kurn's depression.

The producer considered the possibility of bringing back Rodek, son of Noggra, but the follow-up never happened on screen.
