This story is a sequel to Elementals of Harmony
A collection of stories set in the same Multiverse as Elementals of Harmony. Among other things, you will learn about Lyra's employers, how Equestria was made (really), and whether Luna snores.
A Friendship is Magic: the Gathering crossover, like its predecessor. Reading Elementals first is strongly recommended, as there will be spoilers.
Categories have been chosen in light of the wide range of tone.
