Deadly Kartharaddi Clockwork Musician (artifact)
A human shaped automata outfitted with what can be assumed to be high Kartharaddi fashion from the era of the Imperium's downfall, this automata is designed to adequately play a Kartharaddi variant of the flute. As its performance winds down the devilish contraption lowers the instrument and launches a dart from a crossbow-like mechanism cleverly hidden behind one of its 'eyes', hitting whatever or whomever is unfortunate enough to be directly in front of it. A clever, if likely difficult to pull off method of assassination.
