Glass Sphere

A glass sphere is generated when a player enters Byatis.

Generation
Whenever a player enters Byatis, a glass sphere is generated, centered 1 block beyond them for X and Z, meaning they spawn on the floor of the inside. Every time a player enters Byatis, a new sphere is generated in the same space, making infinite farming possible (but what are you gonna do with excess prismarine glass and chiseled prismite bricks?).

Though a new one spawns every time someone goes through a Byatis portal, there can only be one at a time in any given world. No matter where someone enters Byatis from in the Overworld, they will always spawn in the first glass sphere.

Blocks
Glass spheres consist of prismarine glass, chiseled prismite bricks, bedrock, and 1 Byatis portal block.

Warning!
Do not build anything inside a glass sphere, as it is re-generated every time someone enters Byatis (including the air blocks on the inside). This will be fixed in the next update, though, which will also make prismarine glass and stuff non-farmable (and change the bedrock to obsidian).

Lore
Part of the magic used to channel a gateway between the overworld and Byatis draws in solid matter, displacing the water around it with a large bubble of air. Matter slowly builds itself around this bubble, forming a large sphere of protection against the hostile world of Byatis.
