Obsidian platform

The obsidian platform is a 5 by 5 square of obsidian that is generated once a player enters the End. (Note that if the obsidian is destroyed, or if a block is placed on top of it, when the player enters the End, the obsidian is restored and any blocks on top of it despawn.)

Generation
Obsidian platforms generate at X, Y, Z = 100(100.5), 48, 0(0.5), mostly far away from the island, making it tough to get there. Players who enter the end spawn at X, Y, Z = 100, 49, 0 and the other entities that enter the end spawn at X, Y, Z = 100.5, 50, 0.5, the middle of platform and 1 block higher than the platform. Sometimes the platform generates inside a case of end stone. Enough end stone is removed so that the player can walk around. Occasionally the platform generates in midair.
