Admiral Griff was the Fleet Admiral in charge of the construction of Darth
Vaders Super Star Destroyer Executor.
After the destruction of the first death star Admiral Griff was put in
charge of the blockade of Yavin 4 to stop the
rebels from fleeing of planet. Vader was taking his newly christened
ship to Yavin 4 to finaly wipe out the rebel base there.
The rebels however managed to mount a strike against the Executor
and using a power gem disrupted its sheilds and caused enough
damage to delay the Executor. Meanwhile Admiral Ackbar mounted a
diversion attack on the Imperials in the Vallusk cluster.
While the Imperials diverted some of their force to deal with the attack,
an opening in the blockade enabled the rebels to evacute Yavin 4.
Admiral Griff realising his mistake rushed to catch up
with the rebel fleet. To escape Admiral Griff the rebel fleet
where forced to steer their fleet dangerously close
between two flaring stars. Luke Skywalker used the force to judge
when the dangerous solar flares were going to erupt and the fleet
slipped by the stars in the pause between the flares.
Admiral Griff then tried to get past the suns buy doing
a micro hyperspace jump. Unfortunatly he misjudged the jump and
he and his other two star destroyers crashed into the SSD Executor
thereby killing the Admiral. Thanks to the superior shelding of the
Executor it didn't get any damage from the 3
star destroyers crashing into it.
