Gylphs

Glyphs are tattoo-like markings on certain Remnid's bodies. When touched, the Glyph glows and it's attribute is activated temporarily. Remnids that possess Glyphs are called Glyphics. The Glyphic's eyes will become the color of the Glyphs as well, this being a permanent change.

Getting a Glyph
A Glyph is obtained when a Remnid travels to the Isle of Glyphs, located in the center of the Mediomension and gives up something important to them in exchange for an ability from the Universal Power.

Prevalence
Most Remnids are not Glyphics, and most Glyphics have only one Glyph, the exception being Guy Contact who has three.

Known Glyphs
Guy Contact has three; one on his forearm that gives him super strength, a second on his ankle that gives his super speed, and a third on his back that helps him sleep at night. The rarity of his three Glyphs are due to the strength of his sacrifice; he made it so that everyone in his home world forgot about who he was. His family is currently unaware of his existence. The Glyphs are crimson red.

Nama Chan has one Glyph located on her chest. It is purple, and nothing is known about the Glyph's power other than her own description of the power as, "a useful trick [she] thought of when [she] was young." She exchanged the power for her right eye.

Agatha Molde has an amber-colored Glyph on her thigh. She exchanged her ability to feel fear for super strength.

Molly DeVosh possesses a green Glyph for their last scene at the end of the novel. Feeling it was their only option, they gave their own life to cure Eileen of her depression.
