Sunset all a Nemesis Plot?

So... Delving a bit deeper into the lore, there are handwritten notes that are found in each of the Ouroboros storylines.

Each hand written note speaks of a dark side to the Menders handing out missions.

Note to self: Finish formatting the collected notes for future reference

Dark side to Ouroboros, Mender Lazarus, Twilight's Son, Mender Tesseract, Mender Silos, and eventually back to Ouroboros again. I don't think it is ever explicitly stated who the letters are from.

The last letter implies that the Coming Storm might never come with the drastic alterations to the timeline(s) that the Menders have been enacting for their pet projects.

What if... Mender Silos (or the Mender Silos of an Alternate Dimension) saw the damage that was being caused by the temporal shifts and protected a shard of reality, and used perfected Nemesis Automatons to repopulate a new dimension that was otherwise a carbon copy of the "World of Heroes"
