Trivia

 * This citadel is very close to the spawn. Face the building near where you spawn and then take a right turn around the corner.
 * This citadel has 7 floors with a final stretch outside that has no teleporter/safety net.
 * This citadel had a poll in the discord asking if it should be revamped. Unlike Tower of Sandy Slopes and Tower of Mild Sunburn, the amount of votes for yes were less than two times the amount of votes for no. Brandiecem0 said that there needs to be a exponential difference, so a revamp of this citadel is questionable.
