Solaris-3 and Teyvat

Scar is a young adult with a slender, tall build and an unsettling yet elegant presence. His hair is spiky, messy white, with a subtle red hue hidden within the strands like an ember that never truly fades. His face is marked by several scars: one on the right side, a vertical one crossing his left eye, and a horizontal one on his left cheek—lines that give him an air of a violent and unavoidable history. His eyes are heterochromatic, the right one intense red and the left a cold gray, creating a dual nature.

Luuk Herssen is a slender young man distinguished by his pale blonde hair that fades into subtle mint tones at the tips, and piercing crimson eyes. He wears the formal uniform of the Startorch Academy Resonator Nursing Unit, a flawless mix of white, black, and gray accented with gold. Fine golden conduits run along his arms—a consequence of Ichor mutation—accompanied by a permanent mark on one hand from which golden blood flows.

He wears silver-rimmed glasses held by a thin chain adorned with blue gems.

He has short, thick, messy steel-gray hair with greenish undertones, striking blue eyes with a reddish ring around the pupils, and a small beauty mark under his right eye that highlights his youthful features. He wears a long blue earring on his left ear and is dressed in a personalized Favonius Knight uniform: a blue cape draped over his left arm and a white shirt with a blue collar.

Nívora is the identity adopted by the Grand Architect, Schwarzloch, the enigmatic leader of the Fractsidus and the story's main antagonist, who hides under the guise of a young student at Startorch Academy. She appears as a short, slender girl with fair skin, looking tender and innocent, characterized by long light-gray hair tied in buns, large green eyes, and winter attire consisting of a white coat with fur details and a dark hat with plush earflaps; however, this adorable design...
