The Crimson Empire trilogy was a letdown. Excellent first part; okay second part; pointless third part which only rehashed the “resurgent Empire” trope that had already been played out by the end of the '90s instead of realizing the trilogy’s raison d’être (the last of Palpatine’s Royal Guards seeking vengeance against Luke).
Feel that it would have been better if it was the last stand of the empire
A sequel trilogy of trilogies of sort
The rise of the imperial remnant in the Thrawn trilogy
The height of the imperial remnant and the beginning of its decline after Palpatine’s final death
The fall of the imperial remnant after the fall of the last of Palpatine’s royal guards
