Alex is a broad-shouldered half-elf with warm brown skin, thick dark curls worn tied at the nape, and a face that seems permanently on the verge of delivering an amusing observation. He occupies more room than he intends, leaning across tables, spreading maps over other people's belongings, and gesturing with his whole body when he speaks. His hands are unusually distinctive, with flattened fingertips, callused palms, and tiny ink stains worked permanently into the creases from years of copying music, repairing instruments, and handling old manuscripts. He dresses in a rust-red wool coat over a cream shirt, with a silver-stringed viol case strapped across his back.

Alex is warm, nosy, and relentlessly attentive. He remembers small preferences, finishes other people's quotations, and asks questions that sound casual until everyone realizes he has mapped the entire conversation. He is generous with praise but suspicious of effortless certainty. Around strangers he performs confidence, yet among trusted companions he becomes quiet and intensely practical, repairing straps, annotating maps, and making sure everyone has eaten.

Alex was raised between two worlds in the river city of Namarra, the son of a human bookbinder and an elven conservator of oral histories. He learned early that knowledge did not live only in grand libraries. It lived in wedding songs, market arguments, children's rhymes, and the small corrections people made when retelling a story. His first instrument was a damaged viol recovered from a collapsed archive, and he taught himself to play by matching its notes to fragments of old ballads. His music eventually became a way of preserving endangered histories, especially those that powerful families preferred forgotten. At twenty-six, Alex discovered that several supposedly unrelated legends described the same vanished city, one whose sealed vault was said to contain a record of every treaty, betrayal, and secret bargain that shaped the region. He joined an expedition funded by competing scholars, only to learn that one patron intended to destroy the archive once it was found. Alex escaped with a partial index and the guilt of leaving three companions behind. Since then, he has traveled as a performer, researcher, and professional nuisance, using charm, magic, and inconvenient questions to protect the truth. He believes the lost city is still reachable, and that someone is actively hunting the people who know how to find it.
