Welcome to Gaia! ::

The keep stood dark against the mountain in the night, silent and forbidden. Guard was heavy, spells glimmering at every corner. It was here in the keep where the Nightingale was kept. The Nightingale… countless stories have been told, countless legends. This treasure of lore is a gift… and a weapon in the wrong hands. Only one of great power can force the Nightingale to bend to his will. But there are others who command it. The Nightingale chooses three guardians, and only they alone can use the Nightingale’s powers.
They are the only ones who can touch it… and they are the ones that protect it. Meanwhile, far in the keep, was a giant iron door. Elegant carvings decorated it, but the decorations were more than an artist’s fancy. They were spells, cast to keep the Nightingale safe inside. Shadows lay all around this door. From them, a figure stepped out. A sword was held at the ready, poised to strike, while its wielder, a man, glanced around in a calculating manner. There was a stirring. The man froze, crouching in a fighting stance.
Two more figures detached from the shadows, one carrying a bladed staff, the other also carrying a sword. The man relaxed.
“Don’t do that. I thought you were an enemy.” One of the newcomers grinned.
“ I am. I was going to launch a surprise attack on you.” The other rolled his eyes.
“Can we dispense with the pleasantries? Did you feel it or not?” both of the others became serious, nodding.
“Yes… something is here that shouldn’t be…” the first man said quietly, looking around swiftly. The second man rolled his eyes.
“Well of course! I wouldn’t come if it was suppose to be here.”
“Be quiet, you idiots!” the third hissed suddenly. “I sense something… and it’s very near.” They all went quiet. Suddenly, they staggered. Wave after wave of blackness bombarded mentally against them, pain stabbing them relentlessly. The first man gasped in pain, almost dropping his sword. All at once, the pain stopped, and so did the blackness, leaving the three men reeling.
“What… was that!?” the third man moaned, leaning heavily on his staff, sucking in air.
“I don’t know, but… what in the god’s name?” the others turned swiftly, and came face to face… With a solid wall of mist.
“What is this?”
“I don’t know… I don’t think I can fight a cloud though.” The first man said nothing, examining the mist carefully. The mottled gray-and-black cloud shifted and floated but it stayed in one spot a few feet away from them. Another intense feeling of darkness radiated from nowhere again, but without the pain.
“I think the dark feeling is coming from the cloud…” the first man began to say, but then a bolt of white hot pain lanced through his shoulder and he cried out in surprise, the others jerking their heads in his direction in surprise, and then as if it had been being held by flood gates the mottled mist surged forward and engulfed the three men and the iron gate of the Nightingale.
There were no screams.

I agree with froggy06m. Keep up the good work. I'd like to see more of this!

Its quite good, and I liked how you described the setting quickly and simply, while still maintaning (sp?) detail within the prologue. There's nothing I would change, unless I missed something during my read. Bring on Chapter 1!

Id extend the dialougue a bit more in some places, change a few phrases.

All in all, i like it. Id be more then willing to start into this book. Lets see chapter 1!
