Apparition

Abstracted blocks are concealed from the view of the player: they do not affect light, and water still interacts with them. Mining an abstracted block with the right tool always drops that block itself, while matter blocks normally drop something else. Nothing can be placed inside an abstracted block, and gravity blocks fall away into thin air, hanging suspended mid-air until they are actualized again.

Light sources are the one exception. Blocks that already emit light keep that property when abstracted, and a torch abstracted and then toggled still emits light level 15 once toggled off. The concealment setting can be switched on and off, so the effect is a per-block choice rather than a fixed rule. A server running it needs every connecting player to have it too.
