Raboniel (The Stormlight Archive)

"Is it better to have more abilities, or to have one ability handled expertly? We of the Fused know our Surge with an intimacy a Radiant will never know."

- Raboniel to Venli

Summary
Raboniel is one of the Fused scholars on Roshar, and a formed member of the Nine. She was the central organizer of the attack on and occupation of Urithiru, and played a majour role in the discovery of Anti-Stormlight.

As a Fused, she is an individual of great age, existing since the days that mankind first came to Roshar. She fought in the Singer armies against the encroaching human army, though was betrayed by her Gods, Honor and  Cultivation, and wound up joining with  Odium, who granted her and her kin Forms of Power and the curse of immortality.

Though in the end they lost the battle of the First Desolation, and were sealed away onto Braize.

She would spend the next millennia in a cycle of returning to Roshar to try to defeat humanity, but being pushed back to Braize, to only return later. This cycle went on for countless generations, and most of her kin went mad from it. She was one of the few that managed to retain sanity.

During the Last Desolation, she created a disease that was made to eliminate humanity. But not only was it not as effective as she intended it to be, but it effected humans and Singers alike. The death toll brought about was still immense.

During the True Desolation, she took Venli as her Voice, and also served as an important leader in the Singer Military. She was the one to organize the plan to attack Urithiru, occupy it, and corrupt The Sibling, which would leave the Knights Radiant, the central and most powerful force organized against them, without a base of operations. And her plans were ultimately successful.

During the occupation she forced Navani Kholin to do research for her, and in various ways helped her in her studies. This is what eventually led to the discovery of how to create Warlight, a mixture of Stormlight and Voidlight, which revealed that the two were not opposites and were actual compatible. This discovery that they were not opposites also led to a new discovery later on, Anti-Voidlight, which, after she used it to kill her daughter out of mercy, had the method of its creation repurposed in order to create Anti-Stormlight. Which acted as an extreme threat against the Knights Radiant and the Spren they were bonded to.

However, shortly after this discovery she was killed.

Personality
As shown by how she killed her daughter, she believes in euthanasia as a way to put people out of their suffering. Even if it brought her great pain to kill her, she still was happy to end her suffering.

Intelligence: She is a very intelligent individual with an in-depth knowledge of Lights and Tones, along with a degree of Cosmere-Awareness, understanding various things about other planets and other solar systems, such as the Sands of Taldain and the nature of the Cognitive Anomaly in the Nalthian System. She also theorized about the possible nature of Anti-Lights, however she was not able to discover how to make them. Furthermore, she had a in-depth knowledge of pathology and how to create her own viruses and diseases, having made a very potent disease in the past, which killed off 10% of all humans. She was able to quickly understand complex and new ideas with little explanation.

Weakness: She is very vulnerable to Anti-Voidlight, and it can lead to the complete destruction of her soul, preventing regeneration or resurrection. Along with this, the Anti-Tone of Odium causes her great pain and discomfort, and can leave her disoriented.

Fused
As a Fused, she is an immortal being serving Odium, which is capable of using Surgebinding through the use of Voidlight instead of Stormlight. She is unable to be fully killed through conventional means for she is capable of coming back from the dead via possession. Along with this, she does not need to carry spheres with her, for the Voidlight is supplied to her directly from Odium, giving her a basically endless suppply.

Possession
Her method of immortality involves her soul being capable of Investing itself within the gemhearts of Singers and possessing them. his process requires a living singer to open themselves up to bonding a new spren during one of Roshar's invested storms, in the same way as they would to adopt a new form. This process requires consent from the Singer in question.

This causes limited, but still extant changes in the body of the Singer she possesses. These changes solely manifest as a change in the skin patterns of the Host, changing them to match her own. This is used to identify the Singer inhabiting a body, regardless of a change in sex, height, weight, or body type.

Regeneration
She is capable of using Voidlight to regenerate, however, like the Knights Radiant, can still be killed by conventional means. However, being killed only destroys the connection to the physical body, and cannot kill the soul.

Destroying the gemheart her soul is housed in is instantly fatal. However, this still does not kill the soul, it only forces it to leave the body.

The only methods to permanently kill her centre around the destruction of her Soul. Which can only be fully attained by using a Raysium dagger filled with Anti-Voidlight, or through the use of Nightblood

Fannahn-im
As a Fannahn-im, or Ones of Alteration, she is capable of making use of the Surge of Transformation. She is shown to be able to turn weapons into dust and to be able to breath out a toxic compound. She most likely has access to various different transformations.

These Fused are heavily armoured in carapace, with hairstrands present only on the very tops of their heads where carapace is not present.

Pathology
She shows an in-depth knowledge of pathology and how to, through some method, create her own diseases. For during the Last Desolation, she created a pathogen which was intended to kill off all of humanity. However it was flawed, not only was it not as deadly as she expected, it also killed Singers as well. Around 1 in 10 of all humans died, and 1 in 100 of all Singers.

Fabrials
She holds a very deep and knowing understanding of Fabrials and Lights, beyond that of any of the other Fused.

Along with this, she is quite Cosmere-Aware, holding knowledge of other planets in the Cosmere, and of archane items from them.
