Clueless Disembodied Arm

After a long time of flying through the desert, one of Tentako's arms finally found its destination.  Though he had sent limbs to scout parts of the DWMA before, never had he considered revealing his existence to anyone in the Academy, especially not Death himself.  The invisible arm rested on the ceiling for several hours, waiting for someone else to show exactly how the mirror worked.  Getting impatient, it knocked on the mirror three times without writing any numbers and revealed itself to the mirror.  The black-sleeved arm with a pale hand hovered in front of the mirror, waiting for some sort of response and preparing to hide again if anyone entered the room.
