Technological and scientific advancement varies between cultures across Rahymn, but trade is widespread enough that it is not difficult to acquire more sophisticated items from other civilizations in any major city.

The Free Cities and the Ashvadan Caliphate are among the more advanced cultures, having discovered the basic principles of thermodynamics and engineering, employing hydraulic and steam power in their cities, though they have yet to invent the piston (hence the engine either). Mechanical aptitude is relatively high, and clockwork, powered by springs or pendulums, is employed in a wide variety of contexts—not just as clocks, but also as tea-brewing devices, armor-cleaners, weaponry modifications, gambling machines (illegal in the Caliphate), and navigational tools; and many other uses besides. Guns and gunpowder have been employed for decades in [[Ash-Hael]], but while many powers have fully-equipped permanent regiments of gunners and cannoneers, the weapons remain pitifully inaccurate and prone to self-combustion, often costing the gunner’s life in the process. Crossbows are the preferred ranged weapon, though bows are still favored by some for their higher rate of fire and better accuracy over long distances.

Eve as a state has a peculiar relationship with technology, as the church strictly forbids the employment or study of certain very particular fields of science, but encourages the exploration of others. As a result, mechanical and clockwork technologies have reached a level unparalleled anywhere else on Rahymn, and the Evian army is often referred to as “clockwork soldiers,” employing not only weapons but also armor providing added accuracy, strength, and resilience through a variety of semi-hidden mechanical contraptions—they have even achieved very limited flight capabilities. The study of thermodynamics, and thus heat-powered energy, however, is strictly forbidden by the church, significantly hindering the usefulness of many Evian devices.

The cultures of Vordhyal rely less on technology for survival than brute force, partly because the fine metal mechanisms so popular on [[Ash-Hael]] invariably freeze and break down in Vordhyal’s cold climate. The dragonborn of Gunnheim are extremely skilled in the arts of metallurgy, though, and forge the best weapons and armor to be found. They have a peculiar genius for the distribution of heat through architecture, also, though this has not extended to the employment of heat as an energy source. The impregnability of their fortresses matches their interior warmth, and dragonborn frequently boast of being “siege-proof”. Other Vordhyal cultures lag considerably; many are just barely beyond the bronze age, and live in small hunter-gatherer tribes.

The Tuberhood of Rhule does not avidly pursue the physical sciences, but is the most developed among the civilizations of Rahymn in terms of astronomy and architectural engineering. Their buildings are perfectly planed and built entirely without mortar, and their irrigation systems almost rival those of the Lost Empire. Their roads are arrow-straight and flat as an anvil, but bizarrely the wheel was a relatively recent import from [[Ash-Hael]]. Metal is a rare resource on Ghat, so although they know how to smelt and forge steel, most weaponry on the continent is either jade, bone, or occasionally bronze (copper being more common than iron). The exception is the Evian colonies in the south-east, where advanced mechanical devices and steel weaponry may be found in plenty, imported from their homeland to impress and subdue the natives.
