Hiccup
Hiccup had made up his mind. He was returning to Hyrule, if only to ask Link why he left so abruptly. After spending the night on Toothless's back, Hiccup needed some sleep. He decided he would leave later that afternoon. Hiccup commanded his dragon to return to the Edge. Hiccup stumbled into his room, completely exhausted, and fell asleep. He didn't notice the concerned look Astrid sent his way.
When Hiccup woke up, he began packing his things to return to Hyrule. He finished his packing, and fished the letter out of the trash. Hiccup uncrumpled it, and stuffed it into his saddle bag.
"Alright, bud," Hiccup said, walking outside and strapping the saddlebag onto Toothless, "ready to go?" Toothless nodded, looking forward to seeing Reaper again. Hiccup climbed onto Toothless's back, and the Night Fury raised its wings to take off.
"Just where do you think you're going?" Astrid demanded, walking up to them.
"Uh, out for patrol?" Hiccup replied.
"Then what do you need all that for?" Astrid said, gesturing to Toothless's saddle bag.
"I uh-" Hiccup began.
"It's okay, Hiccup," Astrid interrupted, "I know you're returning to Hyrule. I knew you were going to. Just, please be safe. And... bring Link back with you."
Hiccup smiled. "Thanks, Astrid. I promise we'll return soon." Astrid nodded, and Toothless took off. Hiccup looked back at the Edge, and watched Astrid turn from the landing pad, shaking her head slowly.
Hiccup and Toothless flew over the sea for hours. They passed few islands, and those they passed looked deserted. No wonder Hyrule and Berk had never heard of each other. Who would ever imagine a huge continent could be across an ocean so devoid of life? Hiccup mapped each island they passed, navigating to Hyrule on memory, but wanting to create an accurate map anyway.
Finally, the distant Mount Lanayru could be seen, and Toothless flew right towards it. "I'll bet Link's in the castle," Hiccup told his dragon, "that's where he said Calamity Ganon is." Toothless angled himself towards the distant ruins of Hyrule Castle.
As they approached, Hiccup noticed many strange robots patrolling the castle grounds. The robots seemed to be very technologically advanced. As the duo approached, each robot they flew past turned towards them, and put a targeting laser onto Toothless. "That doesn't look good," Hiccup said. "Be ready for anything, bud." Toothless nodded, paying close attention to the robots' actions. One fired a laser, and Toothless narrowly avoided it. Soon, they all were firing lasers at the Night Fury, and Toothless struggled to dodge every one. The pair got lucky, however, and made it to the top of the castle unscathed. Hiccup looked around, looking for anything that could possibly be Calamity Ganon. Hiccup had no idea what the supposed monster looked like, and was ready for anything based on all he had seen in Hyrule so far.
Suddenly, the entire castle shook, and Toothless struggled to keep his footing. "Go into the castle, bud," Hiccup commanded, "that must be where Link is." Toothless flew into the sanctum, and both dragon and ride noticed the huge hole in the floor. Toothless dove into the giant hole without hesitation.
Once inside the gaping hole, Hiccup gasped. In the center of the room, was the back of a huge monster, probably Calamity Ganon. Reaper lay sprawled against the wall on one side of the room, unconscious. Link was pinned underneath the monstrosity. The Hylian's face was white, and he was muttering hysterically to himself. The monster raised its futuristic axe, preparing to end the hero. Toothless wasted no time. He fired up a plasma blast and fired it at Calamity Ganon.
The monstrous beast was not expecting the blast from behind, and lowered its axe, turning around to see who had blasted it. Hiccup quickly noticed all the weapons the Calamity held. He had been expecting something crazy, but not this crazy. Link's enemy wielded a sword, an axe, a cannon, a spear, and pincers. Hiccup knew he and his dragon were outmatched, as the room was too small for Toothless to properly maneuver. Calamity Ganon began walking slowly toward the pair, the glowing skull the monster had for a head seemingly grinning maliciously.
"Um, bud?" Hiccup said shakily. "What are we going to do?"
