Lit
The Illumination, also nicknamed “Ill” or “Lit”, was one of the Abstracts. (COMIC: The Jenny Everywhere Chronicles) He was “the embodiment of the concept of light”. (PROSE: The Disappearance of Jenny Everywhere
Description
Physical appearance
The Illumination had the appearance of a human man, clean-shaven, with pitch-blank hair but pure white eyebrows. Visible eyebags emphasised his anxious disposition. He usually wore a large collar around his neck that kept his powers in check; if he took it off and returned to full power, he was enveloped in a blinding halo of white light, as bright a a newborn star. (COMIC: The Jenny Everywhere Chronicles)
Personality
The Illumination was quiet and even somewhat shy. He was concerned about the effects of his powers on lesser beings, hence intentionally limiting himself by wearing the collar. He wasn't much for self-introspection, having never really thought about what he'd like to be called. (COMIC: The Jenny Everywhere Chronicles)
Powers and abilities
As an Abstract, the Illumination was basically invulnerable, (GAME: The Jenny Everywhere Roleplaying Game) having once displayed the ability to move unprotected in the void of space. (COMIC: The Jenny Everywhere Chronicles)
Biography
Origins
Like the other Abstracts, the Illumination was not always the powerful and transcendental being he was later known as; the Abstracts were created. None of the Abstracts remembered their creation or what their lives had been beforehand, however, (GAME: The Jenny Everywhere Roleplaying Game) although the Illumination stated definitively that he had not chosen the name of “the Illumination” for himself, but simply been given it. (COMIC: The Jenny Everywhere Chronicles)
Travels
Before either of them met Jenny Everywhere, the Illumination travelled with one version of Michael Wherever for a number of years. Michael nicknamed him “Ill”, which the Illumination did not take offence to, despite Jenny's later mockeries. However, they had parted ways by the time Michael joined forces with Jenny aboard the Wilson.
However, some time later, the Illumination crossed paths with Jenny while she was taking a space walk outside the Wilson. He told her he was an Abstract and one-time companion of Michael's; though she did not doubt the latter, she asked him to briefly take off his collar to prove the former. Despite Chuck being worried about the energy levels he'd detected, Jenny allowed the Illumination to come onboard.
They began making small talk, with Jenny noting that the name of “the Illumination” was pretentious and settling on “Lit” as what she would call him — which he rather liked. Before long, however, they were interrupted by an alarm signaling the presence of another, much more dangerous Abstract on the Earth of Universe Juliet-Two-Two-Six: Odious. (COMIC: The Jenny Everywhere Chronicles)
Onboard the Wilson
Some time after “Lit” became part of the Wilson's crew, Jenny disappeared, not just from the Wilson, but from the entire Multiverse. After sending out the rest of the crew to look for ways to bring her back, Michael and “Lit”, left in the ship by themselves, managed to jerry-rig a way for the ship to potentially make a jump into the Infinite to look for any lingering Jennies. Though the procedure was untested and dangerous, Michael's courageous gambit paid off. However, they found the Infinite to be deserted, save for other friends of Jenny's from other universes who had also come looking for her.
Joining up with them, Michael and Lit travelled to a universe home to a seaside town that had been a particularly meaningful place to Jenny across her incarnations, to mourn their disappeared friend. Instead, they ended having to fight off a vengeful entity in Jenny's name, before Jenny finally returned to reality, explaining that she had never actually been in danger, but merely away to replenish her mental shifting abilities in a secret realm beyond Time accessible only to versions of her. Much partying ensues. (PROSE: The Disappearance of Jenny Everywhere)
At some point, the Illumination gifted Jenny a collapsible hard-light knife. It was “godtech”, capable of breaking through even the enchantments of the Faerie Queen. The Jenny of the Collapsed Cosmos retained the weapon, which she used to free Glendalf from a magic tree in Faerie, and in her fight against the Wild Hunt. (PROSE: The Hermetic Garbage of Jenny Everywhere)
Behind the scenes
In The Jenny Everywhere Rolepaying Game, another Abstract with a similar designation — “Rae, Abstract of Luminance” — is featured. It is likely that Rae was intended as a replacement for the Illumination at a later stage in the development of the lore of the Abstracts, although the link has never been drawn in-universe and The Jenny Everywhere Rolepaying Game does not actively deny the separate existence of an Abstract of Illumination.
