Dainsleif is a tall man with light blond hair and distinctive sea blue eyes marked by star-shaped irises—a trait of "pure-blood" Khaenri'ahns like Chlothar, Halfdan, and presumably Pierro and Kaeya. He covers the right side of his face with a mask-like eyepatch, though his right eye remains visible beneath it. His outfit is all business: a black jacket trimmed in blue over a gray vest, black pants, armored gloves and boots, and a black cape lined with a starry, cosmic interior.
Gender: Male

Affiliation: Eclipse Dynasty
Relatives: Vedrfolnir (Older brother)
Dainsleif claims to possess knowledge of fate itself, and his origins remain shrouded in mystery. He's known to have suffered from a curse of immortality inflicted by Ronova—but unlike others cursed the same way, such as Capitano, he doesn't show the advanced physical decay you'd expect. That's thanks to a ring his older brother gave him, which essentially resets his condition over time.
The curse does leave its mark, though. Blue veined patterns trace across parts of his right side—his right arm, part of his foot, his upper right pectoral, and a faint streak along his neck. These markings become far more dramatic when he's actively using his abilities, with the veins lighting up and blackening his entire right arm and foot in a marble-like pattern.
