For ease of Dating, I will use the return of Nightmare moon as my Zero date. Meaning anything that happened before the return of nightmare moon will be referenced as BRNM (Before Return of Nightmare Moon). Things that happened after will be referenced as ARNM (After Return of Nightmare Moon). Hopefully with this reference point I will be able to lay things out in an understandable manner. If you notice inconsistencies send me a PM, rather than comment, since I want to keep this thread purely for Timeline purposes.

1026 BRNM: Knight Watch is born.

This is it for now. Eventually I'll go in and do more elaboration, but this is all for now.
