As the trolls attack, everything seems to slow down around you. A milky white light overwhelms your perception, in a strange way blotting things out even more than the near absolute blackness of the caves.
You cannot tell what has happened to the others, and you have the feeling that you are somehow greatly seperated from the world as you had previously experienced it. There is a presence nearby, something benevolent and somehow something that you feel you have a deep and personal relationship with. It is with you, though you can't say precicely where it is -- it might be to your right, to your left, or possibly even all around you.
*NEED!* The idea overwhelms you, at once simple to understand and also somehow beyond your grasp.
In the distance, you sense a skeletal hand grasping a web of darkness. As it pulls upon strands the web shivers menacingly around the world. Your attention is drawn to a particular set of strands, which somehow seem to extend towards you. The web seems to fall away into the background, and the strands transform into four figures of dark power. One, far larger than the others, holds in his two hands some sort of amorphous darkness, reeking of evil.
You look inside the darkness, and though you remain sheltered in the misty light the dimensions of the dark suddenly seem to exceed your ability to understand. Swimming towards you from the dark there comes a gigantic shark. Your perceptions fall back, and now you see the lake as a whole, as if from flying high above. The darkness fills it, taints it, tries to destroy it. A skeletal finger reaches out, touching the darkness from some far distance, and sharks teem out of the lake, somehow swimming onto the land and hunting outside the water.
*SERVICE!*Another idea comes to you, and before you stands a mighty hammer.
The hammer's head is made from some unusual substance, a form of iron from which magic slips away. Raising the hammer high above your head, you bring it down upon a stone... a very unusual stone. It seems to be an opal, but it's the size of a watermelon. Somehow, the opal is the center of the darkness. The opal shatters beneath your assault, and the darkness shatters with it. Once more, you are alone in the milky light.
The world returns to you, and you are standing in the woods near the farmstead at which you fought the Gargoyles. You are fully healed and rested. The sun is high in the sky, and your companions stand at your side. The presense is gone, and the scrag are nowhere to be seen.
