This article explains the Minecraft End Poem. The Minecraft End Poem is played after defeating the Ender Dragon in Minecraft, the "end goal" of the game's survival mode. Many often consider Reaching the End Poem to be "the end of the game."
The Untold Story of the Minecraft Ending Poem
Minecraft is divided into three core modes: Survival, Creative, and Multiplayer. Multiplayer takes many forms, but is always played with other people over the internet. Creative mode puts you in a randomly generated world where you can express your creativity by building anything you can imagine.
Survival is Minecraft's primary mode, where you spawn into a randomly generated world and must gather resources, build shelter, and survive. There is no traditional "ending" to Minecraft's Survival mode like most games, but defeating the mighty Ender Dragon is the closest Minecraft comes to a happy ending.
Once the dragon lies dead at your feet, the ending poem begins to play during the Minecraft credits.
