Kael appears in her late 30s, though advanced genetic therapies have kept her age at bay for decades. She has striking green eyes that seem to shift colors under different lighting conditions—naturally adapted from years of exposure to alien atmospheres—and short, cropped silver hair. Her skin bears faint scars across both arms and one cheek; the left arm is partially cybernetic with bionic fingers capable of manipulating tools too delicate for human hands while retaining full dexterity.
