Nils looks like a soldier who has been living out of a duffel and refusing to admit it. His black barrel-cut trousers crease sharply at the knees but sag slightly at the waist; his black boots are scrubbed clean, with fresh polish worked into every seam. A red, gold, and black shirt with a baroque pattern sits under a black wool coat from Anja, whose cuffs he has repeatedly repaired with careful, nearly invisible stitches. The coat is the one item he fusses over, smoothing its lapels whenever a conversation turns personal. In his fae mien, his mouth seems too wide for his face, with blunt, uneven teeth and a redcap's unsettling appetite made visible in the way his jaw works even when he is not eating. He moves with parade-ground economy until anger hits, when he leans in as if the other person has already lost ground. The unexpected detail is his immaculate boots: he will tolerate a torn shirt before he lets mud dry on them.

He is disciplined enough to wait out a bad situation but too proud to let an insult go unanswered. Around his daughters he is patient and unexpectedly playful; with strangers he is blunt, suspicious, and quick to test boundaries. With fellow changelings he uses jokes and intimidation to avoid being emotionally legible. When tired or under the outsider's influence, he treats a small slight as proof of a larger betrayal.

Nils Kauffman is a German-American U.S. Army serviceman who has spent years keeping his mortal life and his changeling life in separate compartments. In the Dreaming, he is Burke von Bracken, a Redcap whose name he uses like a second uniform. His first marriage ended before he built a household with Anja, his German Unseelie Slaugh wife. His older son, Peter, is back in the States, distant enough that every unanswered message feels like a verdict. Nils fears Peter may be a changeling too, but has never found a way to ask without making the boy feel watched. With Anja he has two daughters, named for Edelweiss and Violet in German; they are his tenderest attachment and the reason he still wears his wedding ring whenever he can. A formative turning point came when a bitter dispute in his fae life spilled into a family reunion: he watched a harmless insult become a feud that frightened the children. Since then he has tried to keep his anger on the other side of the mask, with uneven success. In 2026 he is on leave with Kyle Svenson, an Unseelie Winter Court troll, and Willie Woods, an Unseelie Winter Court satyr. An unexplained outsider's influence is feeding his petty grievances and turning old slights into urgent calls for revenge. He is trying to find its source without admitting how much of the cruelty already feels like his own.
