Kiloop'ash, the Storm Atronach, was floating inside a confined area, not a cage, but a magical barrier that can trap Storm Atronachs. One of the Bandits was a worshipper of Vaermina and read her books, and knew who Kiloop'ash was, so that was why he was trapped in the cage, for religious purposes to his Daedric Lord. Kiloop'ash moved his rock of a head and saw two mortals, which were Julian and Seven, but he didn't know their names. He did what most Atronachs do when attempting to communicate with a mortal, and telepathically transmitted a message into both of their heads. "You there! Help me get out of here, I don't want to be a slave to these...mortals." Kiloop'ash said to the both of them in their head.
