House Cannith is a human dragonmarked house throughout Khorvaire, although they once were strongly based on Cyre. The artificers and magewrights of House Cannith are responsible for most of the magical innovations of the past millennia. House Cannith made a profit from the Last War by selling arms and warforged soldiers. The house was based in Cyre but because of the Day of Mourning the barons of the house are struggling to take control of the house.
House Cannith uses magical research and invention to remain prosperous. Spellcasters are held in high regard. They use wizards to research magic for new ideas. Their Artificers use these ideas to create the items and their Sorcerers represent the house to the world by obtaining people and things needed by the house. House Cannith tries to obtain any magic resource that can help them create new things to sell.
House Cannith possesses the Mark of Making. This mark grants various magical benefits that allow its bearers to make various items, giving Cannith a advantage in the manufacturing arena.
House Cannith runs the Tinkers Guild and the Fabricators Guild. The Tinkers Guild specializes in maintenance of vehicles and structures, maintaining urban infrastructure, and similar crafts. The Fabricators Guild is divided into dozens of specialties, including architects, elemental binders, alchemists, and armorers who perform many of the wondrous crafts for which House Cannith is especially famous.
