You know honestly this new revelation in Zi-O just has me thinking on how long Swartz could have possibly been doing this plan.

This plan could have been in the works since 2009 with the original merge.

Step 1. Merge the Worlds together to either destroy or create a new world
Step 2. Allow more Riders to be born into the merged world
Step 3. At the peak remove more than half of the Riders and their enemies from history.
Step 4. Allow space time alterations to weaken the world before breaking the things that removed riders and enemies from space and time.
Step 5. Everything begins to get squished together in a rapid pace and thus the destruction of the world from either space time events or Tsukasa decides to do it.
