The Eraser

The Eraser is thought to be a thin structure/barrier surrounding the Metareality-Web. It is also connected to The Pencil. The Eraser is responsible for keeping all things inside the Metareality-Web from getting out, and for erasing any 'bad' or 'corrupt' verses. If any creature touches The Eraser, they will be erased from every single possible timeline in which they are in. When they are erased, they will cease to exist.

First Layer
The first layer is a thin, honey-like substance. If anything touches this, the thing will stick to this layer, and it will be impossible to pull the thing out again. The color of this layer is a pure, glowing white. Some people theorize that this layer is actually a layer of super strong glue. That is unlikely, but, then again, you can't blame them.

Second Layer
The second layer is a solid, Silly putty-like substance. This is the last layer that we can feel. When anything touches this layer, this layer pulls the thing towards the last layer. This layer can pull every type of matter in, whether it is regular matter, dark matter, antimatter, and even negative-sized matter. It can also pull in radiation, light, and every single type of energy or force.

Third Layer
This layer is responsible for deleting the thing that escapes the Metareality-Web. This layer is very unknown, and it is impossible to touch this layer, since if you touch it, you will get deleted from every single possible timeline containing you. It's technically not possible to see beyond this layer, but you can still use the weird quirks in some distant reality in the Metareality-Web and pass this last layer. If you do, you will officially be on The Table.
