Sorry for the long wait! :) Credit to Loke Groundrunner for helping me with the plot when I got stuck!
Link's first instinct was to panic, but he knew that would only make things worse. He took a deep breath and mentally counted to ten; something he usually did when he was stressed out. Then he looked around. It was dark and hard to see, but he tried his best anyway. Finally, he could make out something in the shadows; it looked like a door. If only he could get over there.
He twisted this way and twisted that way, trying to wriggle free. Soon enough, the ropes around his legs didn't feel very tight, and after a few more minutes of struggling, they were released. He pulled them out from the rope.
Now what? His hands were still tied; how could he get away from the post?
Then he remembered. He always kept a small, sharp pocketknife in his back pocket. Hopefully Ghirahim had forgotten to disarm him.
Link strained and stretched his hands, trying to get to his pocket. It took him a couple minutes, but he finally reached it and, to his delight, his knife was still there! He carefully tilted the blade upwards and began to saw at the ropes.
His hands were free now, and he took care of the bonds around his waist. Now he could get to that door!
He ripped the gag off of his mouth and strode towards his freedom. Before opening it, he crouched down and looked underneath to make sure Ghirahim wasn't in the hallway. Link didn't see any feet, so he stood up and confidently walked forwards.
Ghirahim materialized in front of him.
"And just where do you think you are going, skychild?" Ghirahim chuckled as he summoned his long, black rapier to his side. It appeared in his hand.
Link tried to run the other direction, but the demon lord waved his hand and bars sprung up in front of Link, blocking his path.
"You cannot run." Ghirahim smiled and licked his lips.
"What do you want?!" said Link, whirling around. A defiant glare shone in his blue eyes.
Ghirahim pointed a finger to the sky and then pointed it at Link. A burst of dark magic shot out of his finger and weaved around Link's body. It lifted him up and started carrying him back into the basement. Link looked down in surprise and wrestled against it, but Ghirahim's magic was too strong. Before he knew it, he was tied to the beam again, but with even tighter ropes. He had also been searched thoroughly, and the contents of his pockets had been emptied out.
"Why are you doing this?!" Link yelled.
Ghirahim flipped his bangs. "I want your courage, skychild. In fact, I desire it so much…I might be willing to kill for it."
"Why do you want it?"
"You will find out soon enough. In the mean time, get some rest…it will be a relief from the days to come." He snapped his fingers and immediately, Link felt drowsy. "No," he mumbled, trying to fight the overwhelming want for sleep, but his eyes couldn't take it, and he succumbed to it.
