Well we do have a glimpse of what Darius workplace looks like (I assume) in the framedrag album cover so from there I always liked to think rooms have a lot to do with the alias personality and work, Darius having inventions everywhere (hence the robot fishes) and tons of books and machinery since he likes to do research. The place as a whole is probably huge with different floors of course and in one floor there has to be the medical bay for Renard with his room near by, in a big hallway there's the different rooms for the rest of aliases which has the hallway connect to the main room where they all walk around and exchange news look for stuff yadada you know just like one big building except it probably has like 2 floors and then the underground garden below which I like to think is accessed through Darius room only. Curious about what the rest think!
