"Good Job Gary, you made it to Cluster II. Unfortunately, you still have many perils ahead of you. First, let us take a quick trip of nostalgia. Won't that be nice?"
When a wanderer spawns in Level 1000, the above voice will ring in their mind. While the voice is talking, you will be floating in the white version of The Void. Is it from the level itself or something else?
After the voice stops talking, the wanderer will have a tour of every level visited in Cluster I. The level will tour from the first level ever visited to the last level they were on. Each level is a version devoid of dangers for perfect touring access. The levels will change from every 5 minutes to every hour depending on how many levels in Cluster I the wanderer visited. There will be a ding 15 seconds before the levels change.
"That's the end of the nostalgia trip. You will now visit Level 1000."
