Hiccup flew above the waters of the archipelago with his buddy Toothless, searching for a new species of dragon that he discovered with the help of the dragon eye, but he wanted to draw it for the book of dragons. The sun was setting near the island they were going and, even though Toothless could perfectly see at night, they had been flying almost all day, so they decided to descend at rest on the island beneath them. Hiccup was collecting some wood for the fire, then, out of nowhere, it started to rain intensely, quickly they searched for cover, fortunately for them, there was a cave not far from their spot. Inside the cave, they started the bonfire, Toothless laid on the floor near it, Hiccup leaned on him and started writing in his notebook. They were enjoying each others’ company when, all of a sudden, they heard a loud noise at the far end of the cave, both jolted and got up to find out who made the noise. They searched everywhere but didn’t find anything that could have made a noise, Hiccup was walking through a tunnel when, unexpectedly, his prosthesis slipped on mud and fell through a hole, rapidly, Toothless flew after him. At the end of the tunnel, there was another cave with runes all over the wall in front of them, Hiccup couldn’t believe his eyes, the runes were glowing, and in the center of the cave, was the dragon they were looking for, its’ scales had a pattern of his skeleton, with the same brightness as the runes in the wall, the dragon was asleep, it was a magnificent view.
