Hello everyone,
I added Stories that take place in my shared ponyverse, named The Black Sun.

Spike the Knight
[Teen] [Action] [Adventure] [Ongoing - Updated 4 times a week]

Back from the North
[Teen] [Romance] [Slice of Life] [Ongoing - Complete on July 2nd]

Knight of Night - Chosen of the Moon
[Teen] [Action] [Adventure] [Ongoing - Updated 4 times a week]

are all part of it. But because the main story (Spike the Knight is still ongoing I cannot tell you exactly how and when the other two fit in, because SPOILERS)
All of them are stand alones stories and no prior knowledge is required for your enjoyment. As the story progresses and more stories are added to the universe, where each of them fits in will become more aperant.
