Unlike other Dwarven Spiders, Aicantar's Spider is docile, and will only move when commanded to move via the Spider Control Rod. The spider seems to make a connection to the person using the Control Rod, as he attacks anyone who shows hostility towards its wielder. As detailed in Aicantar's Lab Journal, the spider, like most Dwemer machinery, will not function when taken out of the ancient Dwemer ruins turned museum and laboratory used by Aicantar and Calcelmo.
