Darth Maul is instructed by The Emperor to journey to a clandestine small moon in a remote system, and await further instruction.
Upon arrival, Maul makes a cursory perimeter check around his star cruiser with use of breathing equipment as moon has little atmosphere but unusual levels of particles creating a dusty mist.
The Emperors mission details finally come through which give light to the cause of this small moons mist, as he is instructed to search and locate a small mining operation hidden away so somewhere and detain its operators for interrogation when he brings them to an Imperial base. Whatever miners are present are to be killed upon Mauls discretion, which allows Maul the ability to spare life if clearly the subjects are of no tactical threat now or could be thought to be in future. Miners would easily fit into the zero threat category, as they have a basic intelligence only suitable for basic repetitive tasks and moon miners are regarded by some as of lesser regard than nerf herders.
Despite this, Maul knows that he will not be able to resist the "sport" of cold blooded massacre as such is to Sith's nature as is ducks to water, he will revel in the opportunity....his only concern is that he doesn't damage his breathing equipment, but as its combat grade apparatus, should not be of too much hindrance.....
