Within a dark room, a looming silhouette of a laptop zooms ever closer to the screen, flashes of strange images hit the viewing apparatus the viewer is currently looking at.

From strange images of blood and viscera to the undeterminable faces of madness and despair, the images bombard you as letters fly across the shadows, each one bigger than the last as the screen turned on with a crimson hue.

A hand, obscured by a black glove, began to type on the keys as the words began to form.

This set of letters was:

The Alterverse Files.

That was when a set of words appeared under the title in a sickening hue of black and rusted brown.

Umbra Edition.

The screen showed some numbers before a file was introduced, marked:

Alterverse File #8103- Anti-Mabel.

(Initiating origin file)

A series of beeping could be heard before a text box appeared.

(Error. Origin file corrupted. For more information on this Alter, locate the comic Gravity Falls: Lost Legends Story Three, Don't Dimension It.)

The file screen vanished while showing an image of the being as several stats appeared below it, loading at an alarming rate.
