The BAMF sound of suddenly-displaced air, followed by the scent of brimstone smoke announce the arrival of what... kind of looks like what you'd get if you crossed a tiefling with a dark elf, and added a fine layer of velvet-like fuzz.

He's brandishing a pair of rapiers (thank you, Herr Stark)- though one of them is held in his tail instead of his left hand. "Sorry to startle you, but it appears you may appreciate some assistance." He has what sounds like a Zemnian accent, but with the sort of faded affectations of someone who's grown used to speaking Common more often than not.

He appears to be doing his best to look non-threatening, despite his unusual (for his world's) appearance, and the fact that he's holding a pair of blades- which are helpfully held toward the cat.
