It had been 300 years since Zerus was lost at the Battle of the Crystal Empire.
It had been 200 years since Starswirl the Bearded passed into the next world.
It had been 100 years since Discord had gone mad and was sealed way in stone.
Luna was not well. Celestia had proclaimed them both as princesses over Equestria after their triumph over Discord, and they benevolently ruled over the masses. Nevertheless, Princess Luna was certain she was hearing voices. They would whisper her name and they would plead for help. She couldn't remember the last day she went without hearing them. It was so overwhelming.
Princess Luna had not slept well the night before. Dazed, she followed her elder sister out of the grand tower of Canterlot, into the frigid winter afternoon. They were to visit the fledgling village of Cloudsdale, where a scant few pegasi called home. Exhausted, Luna hung her head as she followed her sister. Just then, something caught her eye.
"The snowdrops are in bloom." Luna said to herself as she looked at the pure white flowers growing where Zerus' favorite cherry tree once grew. It was strange. Looking at the hanging winter flowers as they poked out through the snow made her feel at peace.
"Luna, are you coming?" Celestia called as she spread her wings.
"Yes sister! I come!" Luna called cheerfully, feeling her spirits lift as she spread her wings and soared into the sky with her elder sister. She knew something grand waited for them at the pegasus colony.
