The Citadel was crawling with countless beings of all of the races that had a membership or other authority like presence here in the Capital.  Asari, Krogan, Salarians, humans, Drell, Hanar, Elcor, and Turians all called this place home in some capacity or another.  John led the way out of the space docks, and saw that there was yet another strange alien species among their group.  "Greetings, Morpher Gerard Honzue, and don't worry about being late.  We just got here as you observed, and so if you have any questions, I'll do my best to answer them on the way to the Citadel Council Tower.  That too has been modified despite the Keepers trying to modify it back constantly, or at least they did until we managed to gain control of the little buggers.  Because of the recent increase of races representing their own species, the meeting chambers also had to be given an increase in size.  Anyway, again, I'll do what I can to familiarize you and yours on the way.  That goes for everyone."  John said, turning to the group behind him as he made his way through the crowds that were always coming and going.  The Serpent Nebula offered defense from attacking fleets, and it was a very beautiful thing to have in your window most days if you lived on the station.  Then there were the army of ships that wandered about the station at any time, as well as countless others that could be made ready and warped to the station in a matter of minutes from neighboring planets all over the galaxy.  The most powerful of which is the Asari Dreadnought, the Destiny Ascension.  The ship was even then passing in front of the space docks, and John stopped to admire the view for a moment.  The elevators in the back of the space docks came up, and John headed that way.  "Head down to the C-SEC offices, where we'll be scanned in, some of us for the first time, and logged into the computer systems.  Everyone has to go through this or admittance won't happen."
