Minecraft wiki entry for The_End, associated text: Once the player enters the exit portal, the "end poem" is displayed, therefore "completing" the game. The player then respawns wherever their spawn is set in the Overworld or in the Nether, and may return to the End through the same portal (or a different portal from another stronghold); the End remains in the same state as the player left it. The obsidian platform is regenerated each time a player enters the End, meaning that any blocks or block entities placed in the 5×5×4 space on or above the platform are destroyed and replaced with obsidian and air blocks.
