The First Sparks
The Imperial I class Star Destroyer Assiduous is a fairly typical example of a Star Destroyer. It is a mile long and bristles with enough weapons to devastate a fair-size city.
The only notable feature is that the Assiduous has red and black markings on its upper surface, where normally Star Destroyers are entirely Imperial Grey.
Two messages were relayed via the Assiduous to the communications facility on Felucia prior to its arrival.
