[Khan had been checking each room on the second floor when he heard footstep and the sound of a door opening. He waited, following the sound quietly, drawing his phaser. Could there be more cultists or was someone else just exploring the place?
He rounded a corner and found himself looking at the culprit, who a bag slung over his shoulder. He couldn't make out the man's face (if he was a man, or rather, was human, Khan didn't think so), which means he probably wasn't a cultist. Still, Khan wasn't overly fond of people just taking things from the tower, particularly not if they were useful, without telling anyone. He was trying to maintain control of this operation, after all; so whoever had just allowed this apparent thief to walk in here was going to need to be disciplined.
He closed the distance some between himself and the other, not pointing his phaser just yet, before he called out:] Who are you? What have you taken?
