A strange leathery substance of unknown origin is used by the Thoth to make bags and containers, and also to write on. The Thoth also have a device which the human protagonist notes resembles a continually burning piece of coal. This device is used as an energy and heat source, to make fires, and as a torch in dark areas. The Thoth also use chemicals and steam propulsion in weaponry. Tweel carries a bizarre firearm made from a transparent glass-like material, which fires poisoned splinters.
