Sixteen

Sixteen ("Grob'baf" in The Pencil Language or Exdak in Future English) is the verse right after Fifteen, and is the 6th verse in the Eleven Chain. It has the property to slowly corrupt a creature/object's information and properties of things the longer they are exposed to it, making Sixteen a very dangerous place.

Appearance
Sixteen, from the inside, is a huge mess of colors and corrupted information. From the outside, Sixteen appears to be a cube with strange markings on it. These markings have not been found to have any real meaning, and are probably just naturally-formed.

Structure
Sixteen, just like Fifteen, has a very messy interior. Random objects, corrupted beyond oblivion, reside here. Raw information is present here, so trying to enter Sixteen would be a terrible idea due to the information corrupting you and turning you into a mess of disconnected information.

16 Fifteens rotate around Sixteen. The reason why they are outside of Sixteen is due to the interior of Sixteen and its information corrupting properties.
