Braedale Eyescream

Braedale Eyescream, sister to Adaelytha Demonsfall, is a sol'Aeldvar warlock. Both sun elf sisters pursued Eldritch magic in order to help safeguard against infectious Eldritch outbreaks (by accident or by malice), but swiftly diverged in their methods. Adaelytha dedicated herself to eradicating Eldritch magic personally through the use of Abyssal magic, eventually (and involuntarily) becoming a voy'Aeldvari, while Braedale joined the Sifters, a secretive group of warlocks who served as the ethics police for other warlocks, willing or otherwise. Adaelytha became one of the only living kinvar who could use arcana, Eldritch, and Abyssal magic, while Braedale eventually agreed to transumption and replaced the anima of her soul with Eldritch, becoming near-immune to Eldritch magic as a result.
Braedale's heavy use of Eldritch magic eventually had a permanent visual effect, turning her eyes neon-green and faintly luminous; she changed her last name to Eyescream in response to kinvaren reactions to seeing her as such a beacon of deadly magic. (Adaelytha also changed her family name, decades before that, when she joined the group of Aeldvari who would eventually become the voy'Aeldvari.)
Unable to "pass" as a non-warlock any longer, Braedale has fully embraced the strength of her magic. She still acts as a vigilante with the Sifters, seeking out and countering any warlock malice or madness, but she has a very personal window into how even good-intentioned warlocks are treated by those they seek to protect from the Eldritch magic that they study. Rather than campaigning for widespread warlock acceptance, she tends to work from the fringes of society, keeping to the shadows where she can do her work unstymied by the horror of the townsfolk.
She also has a demon familiar named Zaozix.
