Origin
The origin of this marker is unknown, though it is presumed due to its effects, it might have belonged to an angry child.

Effects
This marker will attempt to write on any surface it can find, preferably walls (especially white ones), and will beging to write messages filled wth emotions, primarily those of anger, sadness, or fear. These messages typically carry a self-deprecating or anti-father-fgure tone to them. If any attempts to obscure or otherwise cover up the writing, it will glow a bright blue and show through the obstruction.
