Ok, y'all are probably wondering how this is related to the citadel. The council of the citadel consists of five dudes with traffic cones on their heads. This was first introduced during the crystal event, I wanted to incorporate something from og bossfights in the citadel so I thought a group literally referred to as "the council" would work perfectly. As for the rest, this is kinda what the citadel is meant to be shaped like. An upside down cone with rings around it and buildings on top. Collector actually owns one of these rings (although it is a rather small one compared to the rest) and helped with a large amount of the citadel's expansion, hence the blue color.
