Nice timeline, thanks for this.
I missed a few more of the original events than I remembered. The first one I was there for was Grave Danger, but I couldn't afford both treats, so I went with the weapon over the troop. Little did I know the Grave Knight would take a year to show up in one of my chests (still worth it - I'll probably never have all troops, but I do have all weapons, at least). ^^
