Dei is a SuperGod and Onu’s sister. Dei has always been very interested in the history and nature of her ability Mind Link, frequently visiting Qorter’s Library outside of Anarchaon as often as she can to research whilst also unintentionally being very obnoxious towards other visitors of the Library. Qorter is not fond of her at all. The route and tunnels that connect the Library’s bubble and Anarchaon is not a particularly safe path and is home to many hostile entities of the Transcendent ecosystem. However, Dei does not care and unusually, has never once been seriously injured. Onu remains paranoid about his sister’s safety and thinks she is setting herself up to be killed, but Dei thinks that her brother is being silly. Onu was the only Twin that would nearly die whenever they exited their monocosmal cohort so if anyone had to be cooped up safe at home, it really had to be him and him alone.

Dei is allegedly “hypernaturally lucky” and physical harm is very rarely inflicted to her. When she did get hurt, the injuries were typically so minor that they never actually mattered very much despite the fuss Onu makes over them. This has led her to be very careless and carefree when traversing Anarchaon, nearby Beyond bubbles, and tunnels. Her carelessness never seems to pay off, making her detested by many SuperGods—including Onu and Qorter. Qorter has often tried to assassinate Dei but she always catches on and avoids his traps. Dei thinks Qorter is just playing hard-to-get and flirts with him in return.

Dei is able to know Onu’s feelings. However, much like her brother, she does not sympathize with what motivates her twin. Dei is also aware of her brother’s health. Normally being aware of when a sibling was severely injured would be a cause for concern, but considering how much Onu puts himself back together after incidents, Dei remains unconcerned about Onu’s general health much to his disdain. Though Dei is generally much calmer and more collected than her more hotheaded brother who was prone to having breakdowns and outbursts, Dei can often get a bit too excited over her passions for her own good much to the annoyance of other SuperGods.

Dei is very kind towards Tris and Tris is kind to her in return. Whenever she gets the chance (often when the Library was closed for some unknown reason), Dei would ask Tris to tell her stories about the past and hopefully find missing pieces of the puzzle that was the origin of her powers. Usually Dei gets misled by nonexistent links and goes on wild arelari chases afterwards, much to the annoyance of Onu and Tris. Dei wonders about the many stories and secrets Tris harbours and wonders if he truly knows of any links to her powers. Onu thinks that Dei is being ridiculous with her theories and should focus more on surviving in her hostile surroundings.

The Elder is a relatively well-known legendary figure among many Transcendent Ecosystem species such as SuperGods often credited for the creation of the Transcendentem Continuum or Transcendentem depending on the group that discusses him. He is often described as a very powerful Aspect Lord, though few cultures estimate that the Elder's power may have been actually closer to that of a Transcendental Guardian or Greater Guardian. The creation of the eponymous pseudolifeform "Elder's Fire" is also very often credited to the Elder, though it is not actually known if the Fire had Aspect Lord origins due to the lack of substantial, replicable evidence that suggested anything of the sort. The majority of stories about the Elder consistently agreed that he created a deity vaguely similar to those of Least, Lesser, Greater, and Transcendental Guardians creatively dubbed "the Higher Guardian". The story of the Elder and his child is one of the oldest known stories to SuperGods and it is not known when the first inscripverses that recorded the story were created.
