Shadow Side

Shadow Side would be a dimension, or a set of 3 dimensions: one for each current dimensions in the game. The only way to access this dimensions is by using a Shadow Warper. When entering this dimension, the Shadow Warper will transform into a Key Warper, and by using it, we will return to the original dimension.

This is just a copy of every dimension: there is the Shadow Overworld, Shadow Nether and Shadow End. Each block in the Shadwo dimensions, corresponds to 1 block of a date dimension (if we walk 30 block in the Shadow Nether, we walked 30 block in the Nether, or 240 block in the Overworld and Shadow Overworld). In this dimension, we can't break blocks, but we can place them. There are no mobs here, and players form other dimensions can't hit us, but we can see them as ghosts in the Shadow Sides. When accessing this dimensions, we will start to lose xp points, and once we lost them all, we will start to die, by losing health
