Venn D. is a slender warforged built from dark walnut-colored wood, matte iron plates, and narrow bands of tarnished brass. Their face is a smooth mask with a single vertical lens that glows pale green when they are focused. Fine stitch marks and replacement plates reveal years of repairs. Venn wears a close-fitting black hood, a weathered leather coat, soft-soled boots, and a bandolier of lockpicks, wire, chalk, and small tools. Their movements are precise and nearly silent, though their head often tilts at curious angles when studying people.

Venn is observant, dryly humorous, and intensely patient. They prefer to study a room before acting and collect small details about everyone they meet. Venn is courteous to servants, prisoners, and overlooked workers, but becomes cold and calculating around people who treat others as property.

Venn D. was assembled for a war that ended before their makers finished teaching them what victory meant. After the fighting stopped, Venn drifted through abandoned supply depots and ruined fortresses, repairing their own joints with scavenged parts and learning the habits of living creatures by watching them. They discovered that people often overlooked a silent construct in a servant's coat, especially one carrying a ledger, a crate, or a message. Venn began moving goods through locked doors and guarded checkpoints, first for survival, then for coin. Their criminal career began under the direction of a fence known as Mother Brass, who taught Venn the difference between stealing from a tyrant and stealing from someone who could not afford the loss. Venn became a specialist in quiet entries, false identities, and impossible escapes. A burglary involving a sealed military archive changed everything. Inside, Venn found incomplete records about their construction and a reference to a missing unit designation that may identify the workshop where they were made. Venn took the archive's contents, but the information was stolen from them before they could decipher it. Now they travel as an adventurer, pursuing the missing records while accepting carefully chosen jobs. They insist that every locked door has a reason, and every reason can be understood.
