I have been doing a lot of thinking, thus, leading to some fanfic idea (weird how the brain works). Anyway, I'm just having trouble with the main protagonist who is an OC. Unfortunately, I'm having trouble with a name and design. Also, I'm not sure the story would be any good (though I'm sure it will). I need opinion about the synopsis as well...
The story begins with a pony (a pegasus) who wakes in the middle of the mysterious Everfree Forest, miles from civilization. He suddenly realizes that he has no recollection of how he got there and who he is. In a dream, he is visited by Princess Luna, days before her time in Ponyville on Nightmare Night. He reaches Ponyville and tries to adjust to life without his former memory. He decides to live in Ponyville to make new memories as he tries to discover his 'forgotten' past.
The 'story' might as well be like the series, since it follows the same timeline as the show.
This pony is seemingly outgoing, though he knows he is socially awkward at times. He feels compelled to write down his thoughts and 'adventures' in a diary, so he 'retain his memory.' Although a pegasus, he has acrophobia, though no one knows (yet)... (This is all I can say about the character; the rest will follow once I start writing...)
