Vesper has obsidian skin dusted with the permanent grime of a workshop. Their left horn is snapped halfway up, and their intense amber eyes seem to be constantly calculating the stress points of everything they see. They wear heavy, practical scale mail and a bandolier of mismatched tools.

Cynical and deeply suspicious, Vesper trusts machines more than people. They speak to their tools in a low murmur, treating their equipment with more tenderness than they ever show to their allies.

Vesper spent years as the chief engineer for a mercenary company called the Brass Cog. They were a true believer in the idea that hard work and loyalty were the ultimate virtues. If you fixed the engines and kept the gear sharp, you were family. That belief was shattered when their sister, Kalli, and their supposed friends framed them for a high stakes theft they did not commit. They were dragged to a forgotten desert tomb and sealed inside to starve as a sacrifice to appease the locals. Vesper was left for dead in the dark with nothing but their tools and a starving, desperate entity that haunted the burial chamber. Instead of succumbing to despair, they shared their meager remaining water and scrap rations with the dying spirit. This desperate kindness formed a strange, mechanical bond that allowed Vesper to learn forbidden secrets of artifice as the being finally faded away. Using a shard of metal and their last ounce of strength, Vesper bypassed the tomb ancient seals. They emerged from the sands not as the loyal soldier they once were, but as a survivor who knows that the only thing you can rely on is the steel in your hand.
