This story is a sequel to The Vagabond

Continuing tale of Valiant, the former Vagabond, as he and Dr. Mend discover something that will change both of their lives forever. (Pic is Dr. Mend)

A mysterious pony is found on the road to Ponyville. He is brought to Fluttershy's house to recuperate and they discover that he is an outcast trying to be forgiven by the spirit of the mare he accidentally killed. (Pic is Vagabond)

In a freak accident from the Cloudsdale weather control team, Twilight is struck down by an errant lightning bolt. But the veil of death is relatively thin...

Was the usual morning, Lyra and Bon-Bon were sitting on a bench and talking:

Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.
