There once was a time, when the Shadowbolts and the Wonderbolts lived together without argument. The Wonderbolts performed during the day and the Shadowbolts guarded the night, but the day that Nightmare Moon attempted to take control of the country of Equestria, the Shadowbolts followed. Celestia, alongside the Wonderbolts used the Elements Of Harmony to banish the shadowbolts and Nightmare Moon, Their power of light banished the Shadowbolts to what's now known as the Everfree forest, and Nightmare moon was sent to the moon. The wonderbolts and shadowbolts have never been seen together for 1000 years.
What would happen if a Shadowbolt and a Wonderbolt became friends? Would it start a war? Would anypony die in the process to return harmony between the two groups of elite fliers?
A chance encounter could change Equestria's history forever
