i'm sorry, but I've never really enjoyed FanFics.
Frankly, all good literature has usually originated from an original idea.
And anyway, too many fanfics are about "A new pony" that's completely a Mary Sue of the writer that strikes up a relationship with one of the 5 for research.
And then, the rest is Luna.
No hate on Luna, but she's overrated. She's the moon. whoopee.
