Moira had been at the party as well, using her cover identity as Nalia Alderana, upcoming businesswoman and co-owner of Archangel, a droid manufacturing company. Dressed to the nines in a sleek suit and looking the part of the savvy capitalist, polite conversation had been made with Chiss aristos and merchants. Tedious, to be sure, for many of the titled lords and ladies were so shallow she felt an urge to just forego processing and break them in half, but it had to be done and she was quite proficient in fooling organics.
Then assassins had struck, as was expected, a bomb blast had shattered the windows, chaos reigned. While the Governor, another fool who would be terribly improved by a blaster bolt to the head, was spirited to safety and seemingly all across the building fights were breaking out and salvoes of blaster fire could be heard, attackers seemingly popping up everywhere like mushrooms, Moira had discreetly left the ballroom amidst the chaos. Her sensors picked up on Siobhan Kerrigan, butchering her way through the ranks of assassins after concussively beating the traitorous musicians into bone crunching death.
She did not have to way long before, as she advanced towards the sounds of battle, having picked up on the message from the stormtroopers about being under attack, that she happened on assassins herself. Good. Though few organics would see it in on first sight, such was her intricate design, her true nature was that of an assassin droid; the vermin would stand no chance. Producing a concealed blaster pistol she advanced, immediately raising the gun and riddling an assassin with blaster bolts just as the door to the maintenance room opened slightly, the attacker dropping to the ground like a puppet whose strings had been cut even before he was through. She twitched slightly as some shots struck her, momentarily slowing her down, then stormed forward, fast, very fast, no attack seeming to harm her. Grabbing one man she broke his neck like it was a twig, then gunned down his companions using her blaster and his own gun, having seized his arm, broke it and squeezed the trigger, then tossed him at another assassin coming in from an adjacent corridor.
The path clear she advanced onward, gunning down wounded assassins, no exultation on her face, no remorse.
