Glogus, also thanks for your thoughts. I have decided to update my opening text so it does not override any canon. Here it is:
Under orders from Lord Vader,
the GRAND INQUISITOR must find
and execute outsiders who use the Force.
While leading a team of Jedi Hunters
on Tatooine, the Grand Inquisitor
was shot by a Tusken Raider sniper.
Declaring the Grand Inquisitor dead,
Vader orders weekly executions
on Tatooine in retaliation.
