I guess I could give it a shot, to sort of get this thread moving :P Although most of this is already on the go, I have not worked out too many more details, so everything here is tentative.
----------
Basically, you're the generic young hero in a quiet village. One night, you awake, finding yourself rather thirsty, so you head downstairs for a drink. When you get down, you could've sworn you heard something outside, and, despite the rain, decide to take a quick look. You stand in your yard, looking to see what made the sound, when an old robed man runs by, stopping when he sees you. For a quick moment, he stares into your eyes, and you know something's up. Something odd...perculiar even! :O
Anyway, he gives you a piece of a stone tablet, and keeps running before you can ask him anything substantial. Before you can do anything more than stare at the odd stone, Kingdom soldiers appear on the scene. Having lost their target (old man if you hadn't gathered), they turn their attention to you, standing stunned with the stone in plain view. The commander of the squad sends some after the old man, while the rest creep closer, surrounding you. But, although you may not be too smart at times, you can think on your feet, and speedily slide past the soldiers, and hurry away.
You exit the village, and keep running along the outskirts. The soldiers eventually catch up to you, and you find yourself cornered again, with slightly less chance of escape :P The soldiers inch towards you, but before they reach you, the ground collapses beneath your feet! *suspense*
The soldiers stand around the hole, staring into the blackness. Normally you would be pursued, but being the generic lazy soldiers that they are, they decide that it would be more practical to wait for you to climb back up, if you even survived the fall.
Of course, you survived the fall. You find yourself in a very dark stone passageway. When you come to your senses, the passage is suddenly flooded with light. As you walk down the symbol riddled hallways, you find yourself in a large open room. The light intensifies, as a ghostly figure appears in front of you! *more suspense* He says a few words, which, although in your language, make next to no sense to you. After the figure generically disappears in the middle of an important question, you find a rope in the corner of the room. With nowhere to go, you take the rope and head back to where you fell in. As you sit wondering how you're going to get out of this strange place, the 'magic rope' leaps from you and attaches to the wall. Taking your chances, you climb back up into the night.
Luckily for you, the useless soldiers had fallen asleep. You sneak past them, battling with the fact that you can't go back to your village, at least not for a while. You force yourself to keep running, as the sun creeps over the horizon. Unfortunately, the Kingdom is still at your heels, and you are captured.
NOTE: There is a lot of details after the capture, but I'll leave them out, as not to spoil everything.
To make a long story slightly less long, you are forced to join the Kingdom, and help them find the true power that they are seeking. But the Kingdom is not alone in their search. The Serianes, a rogue group who don't agree with the Kingdom's ways, are massing together to find this power first. You find yourself in the middle of the monumental battle for power, and as the world takes sides, you find out who is truly the enemy.

So, that's basically my ideas in a nutshell.
