This survival world was originally created by Yellow Flare on Education Edition since on the year 2021. It was a personal world where him and his friends would play and hangout. However, due to some factors in the past that prevent him from opening the world more often, like a time limit, the world was given to RandomV!deo 124 (Elijah) since he didn't had a time limit and could open the world anytime he likes. Elijah decided to make Versions of the world as a way to save old copies and if there was major updates to the world like addons, converting, etc. However, slowly but surely, the friend group joined the world less and less and only Yellow Flare and Elijah only played the world the most since Version 2. 

Overtime, Elijah realized that he could lose this world if he ever graduated from high school since the world was an education edition. Thanks to NBTStudio, Elijah figured out on converting the Education world into a Bedrock Edition world. With this, Elijah made a Custom Education Cape for it (Which is not available anymore) and a custom block that's fused with a grass block and a bookshelf block, which would explain why you might see unknown blocks in the world.

 So far, Elijah mostly has been building and adding more into the world for a few years as he cares so much about this Minecraft world, pretty much making the Minecraft world a big project. 

For more information on the world, the world itself also provides history of what happened in the Minecraft world, from countries, wars, acts, and much more. You could also look around the website for more information on the Minecraft world too.
