This story is a sequel to Snowblind
After the restoration of Gertrude's sanity and the awakening of the Snowheart clan, everything should be fine for the former Element of Generosity. Unfortunately, the Griffon Empire isn't sure that it wants to have to deal with an ancient, immortal ruler returned from a bygone era. A diplomatic envoy led by the Emperor himself has arrived in Equestria to determine exactly what place, if any, Gertrude and her followers have in the modern world.
Along for the ride is an old friend of Rainbow Dash's, who's apparently come back to make Dash's life miserable.
