One day, the Crusaders happen upon Ponyville’s newest, specialty flower vendor: a young mare from Alemaneia named Schneeblume. They think she’s hiding something. Turns out she is, though not in a way they expected at all.
While the scars of the War will forever remain, Schneeblume has been helped along by the three Crusaders over the years. Now, she must lay to rest some more demons that have haunted her. To do so, she must return home to where it started: Alemaneia.
A meteor impacts the nation of Equestria, Planet Equis. Tranquility is quickly snuffed out when a poison begins to spread violently. The Princesses cannot combat this unknown threat, as no knowledge of it exists. Help comes from an unexpected source.
