The Daedalus is on a routine mission when it receives a message from the Regula Class station Pericles. They’ve been working on the Unimatrix and requesting further assistance in examining it.  They arrive to find an empty station fully powered.  The former crew of the Rhode Island starship arrive soon after, having received the same message.  Something is amiss.  The teams transport over and find the station has suddenly locked down, preventing transport.  Scans show the Unimatrix is active…and so are other previously hidden signals.
