Chronicles of Farn is going to be a Fantasy story that has some Slice of Life elements to it, but is also about the rise of the greatest hero of all time, who is somewhat of a Mary Sue (based on me, absurdly strong in too many ways), but one which I go out of my way to justify in the writing.
(Specifically, a big part of the reason for things going right for her is, well, duh. She was summoned to the world to do specifically those things. The spell specifically is worded in a way that guarantees the person summoned will be incredibly competent at, effectively, anything they need to be competent at in order to save the world in the way they are meant to, in the way they were summoned specifically for. Many of the forces which give her power can see into the future to select her specifically, combined with the spell summoning her, combined with her innate talents.)
I've been working at it for the last couple weeks or so, and it's a combination of an old old old idea (circa 14) that was heavily Adventure Quest/DragonFable inspired, and a new "what if" that boils down to: "what circumstances would be required for the protagonist I have in mind (that is heavily based on me), to be the one summoned?"
Basically, no matter who would be summoned, no matter what, they would ask the question "why me?" why that person, out of the over 7 billion candidates which could be selected? Well, when you go out of your way to justify that, they you have a fairly interesting story idea I feel about a character who is effectively a justified Mary Sue.
That said, I don't truly consider her one. She's not lucky per se. She's not the best at everything. She's not talented in literally everything. She's a jack of most trades, 8-9/10 in some/many (but not all). Good at more than most people are, but not the best at anything.
Her achievements are believable, given the setting. Her main strength isn't in her strengths but in her personality, which is not perfect. (Admittedly though, many of the flaws in it only appear in the sequel.) She befriends individuals and uses diplomacy first, with fighting done only when needed. But it's justified, not perfect, and has notable drawbacks.
I love the story. I just need to make it now.
But boy oh boy is it taking a lot of time.
