Why there, you ask? Whenever Leviathan performs any maintenance we have to maintain a completely sterile environment to prevent unwanted "intruders" from entering the vessel. While the microbes and viruses in the air may not seriously affect humans, one "cold bug" has the capacity to kill a large section of our crew.
The last time Leviathan had an extended breach happened to occur while two members of Freedom Force had a mild cold. Two virus managed to get into C deck, consuming 284 crew members before we were able to destroy them by flooding 50 decks with chicken broth. [Provided by Alche-Miss. We managed to take a sample of the broth for replication purposes. It has been a big hit with the crew. Except for the 27 crew members that were still in the flooded decks at that time.]
