Obsidian platform

The obsidian platform is a 5×1×5 square of obsidian that generates when a player enters the End.

Generation
The obsidian platform generates at coordinates (100, 48, 0), mostly far away from the island, making it tough to get there. Players who enter the end spawn at coordinates (100, 49, 0) and the other entities that enter the end spawn coordinates (100.5, 50, 0.5), in the middle of and 1 block higher than the platform. Sometimes the platform generates inside a case of end stone; enough end stone is removed in this case so that the player can walk around, with 4 blocks high of breathing space. Occasionally the platform generates in midair.

If the platform is destroyed, or if a block is placed on top of it, the platform is restored and any overlaying blocks on or within 3 blocks above the obsidian are removed when the player enters the End.

The platform only generates when an entity uses an end portal, not when teleporting with.
