Knariit'ash watched as the figure, now recognisable as the Orc who'd left the city with the girl, entered the tower. Once he'd disappeared into the structure beneath him, the Imp waited a few moments to allow him to make some progress into the building before drifting silently to the ground and making his way back inside, behind the Orc. Knariit'ash was large for an Imp, albeit nowhere close to the power of an Orc, and could just about hold his own in hand-to-hand combat due to his agility and the extra advantage provided by his razor-tipped tail. Still, he preferred to avoid head-on encounters if he could, preferring to attack under an element of surprise. Many would call him a coward, but he saw it as being closer to logic than cowardice.
He figured the Orc would have headed upwards and made his way to the stairs, quickly finding his assumption had been correct as he rounded the corner onto an intermediate landing and saw the Orc almost at the bottom of the next flight of stairs. He decided he'd have more of an upper hand here, in the close quarters of the landing, where the Orc was likely to be cramped and seized his opportunity, pouncing at his turned back, claws extending even as he left the floor. In his enthusiasm, he let out a quiet but definitely noticeable shriek of malice which he immediately regretted, as he realised he'd blown his cover before taking advantage of the Orc's obliviousness.
