Minecraft wiki entry for The_End, associated text: All players begin their exploration of the End with the main island. Unlike Nether portals, entering the end portal instantly teleports the player to the End, giving no time to back out. Upon arrival, in the end, the player materializes on a 5×5×1 obsidian platform with 3 layers of air blocks above it, if there are any blocks in a 3 block space above the platform, they are deleted upon a player entering an end portal. The platform can generate on the island, within it, or at a short distance from it, close enough to throw an ender pearl to reach the island. It always generates centered on the coordinates (100, 49, 0) with the player facing west.
