Since the building’s computer was in control of all of the security systems, Ariel could access and control them through her link to the computer system. The security subroutines were of course protected by access barriers and more ice, but Ariel had cut through enough ice in her time to know what to do. A wave of her wand and a pinch of fairy dust produced a ring of old-fashioned skeleton keys that jingled pleasantly (an added sensory touch Ariel was quite proud of). A complex matching algorithm ran, and one key presented itself at the top of the ring in the silver fairy’s hand. Ariel stepped over to the chrome-and-circuit-covered wall of the host system and inserted the key into the slot that appeared there.
