"Now can we go into the twilight?"
Bark! Bark!
Crap.
"Geez, someone is impatient. We'll be there soon, just head to where the wall of twilight actually is."
How did she understand him?
"Wait..."
Link turned around. "Midna?"
Arf!
"Come...to my spring..."
Link peeked into the spring, and his heart felt heavy.
Link poked Ilia in the stomach, but she grabbed his finger. He tried to twist it free but she held firmly, so instead he poked her with his other hand. She giggled and blocked her stomach with her arms.
He shook his head and began to walk toward the spring. He saw something floating there...light...a spirit, maybe? But it had no real shape...
"You have...been transformed...by the power...of shadow..."
That definitely wasn't Midna.
Link bowed his head in agreement.
"Come to me..."
He walked forward a bit, and walls suddenly appeared all around him.
Whatever the walls were made of seemed to be the same kind of energy the twilight wall was made of. It was just high enough that he couldn't jump over it.
"Beware...a shadow being...it approaches..."
Something above him, way up in the sky, appeared. It also appeared to be made out of twilight magic. Something large and black fell out of the portal...Like the shadow vermin he'd seen in the sewer - but a hundred times bigger.
Great.
He backed up to the wall, but the energy shoved him to the ground. The giant shadow thing lunged at him and Link felt pain shoot through his side. He ran away from it, then, without a second thought, lunged at it.
"Link, what in Nayru...?"
"Not now, Midna!" Link shouted, or, rather, barked, as he slashed his claws into its skin. It took some damage, but was still fighting. One more hit and it would be dead.
Never once did fear cross his mind as he lunged at it again. This time he sunk his death into it, and it collapsed under him.
Link backed off of it and watched as it broke into a million bits, which were carried into the portal. Which stayed.
The walls, however, disappeared. The water and stones around him were bathed in light, and a small orb appeared in front of him. He watched as light suddenly extended from it, and a magnificent creature, unlike anything he'd seen, displayed itself before his eyes.
"O brave youth..." it said slowly. The more he looked at it, the more it looked like one of the Ordon goats.
"I am one of four light spirits that protect Hyrule at the behest of the gods. I am Ordona."
So maybe it was a goat.
"The black beast you slayed was a shadow being. It had come to seize the power of light I wield."
The twilight...
"My brethren in Hyrule have already had their light stolen by these fell beasts," it explained. Did that mean Ordon was the only place not overrun by twilight? "The entire kingdom has been reduced to a netherworld ruled by the cursed powers of darkness. The blight will not stop with Hyrule. Before long, the entire world of light will fall into the hands of the king who rules the twilight."
