It was a typical day and Kumorii was down in his mine, looking for diamonds like usual when it hit hit him in the face like a brick. "I wonder how difficult it would be to battle the Ender Dragon by myself.." he though. It was then that Kumorii hopped in the minecart and began the lengthy ascent to the surface, where he would have to take another ride on the short rail to his second base where he had stored some Ender Pearls and Eye of Ender's. He crafted a few more Eye of Enders and got together a bow and plenty of arrows. "I sure hope this goes well!" Kumorii thought. Without a second thought, he proceeded to follow an Eye of Ender to the nearest Stronghold.
After trekking over a ravine and several hills, Kumorii found himself face to face with the ocean. This wasn't about to stop him from reaching his goal - He had a dragon to slay! Kumorii quickly chopped down some trees and crafted a boat on the spot - leaving behind the crafting table. After roughly 10 minutes of bland sights in the ocean, he finally was sitting above where the Eye of Ender had indicated the Stronghold to be! Kumorii planned this would be a pretty interesting operation so he built a quick shelter on the surface of the ocean and a glass tunnel to descend to the ocean floor and reach the Stronghold.
Kumorii quickly put the supplies he expected to need in his inventory and the immediate requirements in his hotbar. He placed a bed in the corner of the room and slept there in case of any unfortunate deaths. He then proceeded to place a chest on a ledge next to him and put the remainder of the items he wouldn't need inside of it. He walked up to the platform and placed the twelve Eye of Ender's in their frames and fortunately had one left over. He looked down at the portal and thought, "Well, here we go. This is the end." and with a nervous gulp, dramatically jumped into the portal.
When he landed, he could make out the purple-tint eyes of the Endermen on the land in front of him. After some evaluation, Kumorii shift-stepped to avoid stepping over the side and made an obsidian bridge to the floating yellow mass of land in front of him. He was overwhelmed by the sheer number of Endermen until something shoved him a good 20 steps away from where he originally stood.
With a quick glance up, he saw a dark mass with grey wings flying away from him - The Ender Dragon.
Kumorii quickly paced his way towards the closest of the obsidian pillars and climbed it by building a mildly-inconvenient staircase of obsidian and keeping a distance, shot the energy crystal with an arrow. Unfortunately, Kumorii still took considerable damage and got pushed off the side of the pillar! Fortunately, he landed on a block from his staircase. "That was too close!" he thought, as he waited for his health to regenerate and hopped down to the ground, losing three more chunks of health. Kumorii repeated the process until he was finally only one well placed arrow away from the final pillar and with a "kaflunk" of the bow, destroyed the last of the energy crystals.
The battle was fierce and long. The dragon would sweep down at Kumorii, only to be greeted with a barrage of arrows. Eventually the dragon was clearly one-shot away from death and Kumorii made sure to get the perfect shot. "Just a little closer.." he thought as the massive dragon charged towards Kumorii, whom had his bow drawn and ready to make the shot. The arrow split through the air and directly into the dragon's head. To Kumorii's surprise, the dragon froze and began emitting a brilliant purple light as it seemed to burn away in some sort of invisible flame. He had succeeded in his journey.
With roughly an hour well spent, he returned to his ocean-top base before returning home and then it hit him - He didn't bring a map with him and had no idea how to get home.
