Most ponies of Equestria let this particular day go by without so much as a second glance. Some historians or mages acknowledged its existence, but only in the context that the world lost a great spell caster, and with him much untapped knowledge. Nopony saw it as a day worth commemorating, worth remembering as more than a trivia question.

Yet, for Princess Celestia of Equestria, it was the day she’d lost her best friend. So she takes the time to reflect on their friendship.
