Believing that the Klingon Empire had grown weak and lost its way through its peaceful interactions with the Federation, Dorg sought to destabilize Federation-Klingon relations using the Pakleds as a proxy. Dorg supplied the Pakleds with various Klingon weaponry, and provided Rebner of the Pakled Clumpship  with a Varuvian bomb, for a plan to smuggle the bomb to Earth.

After Dorg ordered the Che'Ta to open fire on the  and the Sh'vhal, Ma'ah killed him to prevent the battle from continuing. Ma'ah then ordered the Che'Ta' to retreat from battle and report back to Qo'noS. ()
