Be careful what you wish for.
Feeling progressively more and more disillusioned with his actual reality, Will revels in escapism. Of course, he never expected to wake up one day and find that he had actually been summoned to another world!
Essentially shanghaied into performing an absurdly difficult task that would have perfectly suited one of the fantasy epics that he used to love reading, Will is in trouble.
After all, the common sense of his old world doesn't really apply in a reality where magic, beastfolk-type demi-humans, and literal monsters are considered just a part of everyday life.
If he doesn't get up to speed fast, and find some people he can trust as he flounders around crippled by his sense of inadequacy, he's going to end up deader than dial-up.
Still, if this is an epic fantasy story, and he is supposed to be a hero, he must be a main protagonist ... so ... no matter the odds, if he doesn't give up, everything should turn out fine ... Unfortunately, convincing himself of that is an epic task all of its own.
With the fate of a world literally cracking apart at the seams hanging in the balance, it's going to take skill, grit, and a whole lot of luck to succeed ... but one out of three isn't so bad when starting out, right?
