As trade continued with the Hashas, the peculiar art of Geo-Botanical Prospecting was picked up, as several experts were hired to help look for valuable metal or mineral deposits in Arath.

From the Radeti came a number of technologies. Hand Pumps were a massive time saver for the drawing if water upwards, and inspired several innovations by the Arathee similarly dealing with water. Welding was picked up by a seeker, who was making her way through villages and small towns when she ran into a blacksmith less protective of his secrets then most.

Finally, there was the Scutum, the result of a collaboration of military thinking of the Arathee and the Radeti. When ---- first saw the difference in effectiveness between the loose Arathee fighting line and the tight Radeti center, he approached them to try and better understand the methods and strategies behind it. As this interaction broadened into a lively discussion over the course of several weeks, one of the key questions that was asked by a junior commander inquired as to what the optimum spacing of troops in a formation was. While troops packed tighter together would be more effective against infantry or cavalry, past a certain point it isn't feasible because of the shields. ----- answer to this was why not change the shields? Despite the influential role the Arathee played in the development of this design, they lack any experience on phalanx warfare beyond what wisdom the Radeti have shared.

With the adoption of the hand pumps, better means of transporting water were needed; the old system of ditches and canals just simply didn't work that well. The inspiration for Pipes came from the design of the pump itself, as a natural extension of the mechanism. The majority of these pipes ended being made from lead, despite the health effects known to plague both miners and smelters of the stuff. While various methods were advertised to the rich, from a simple whitewash on the inside to pipes coated with silver, no one really checked after the pipes were installed.

Pulleys were an essential labor saving device for the Arathee. As stone was the primary building material, being able to actually lift the blocks tended to make building projects go faster. For over a thousand years, the three-pulley-crane had been used in virtually every project that required blocks heavier then two men could lift. It was with some surprise when an architect (currently lecturing on the subject) was asked a question by a boy of 6: "Why only three? Couldn't you just add more pulleys?" While the Five-Pulley-Crane wasn't quite that simple to design, it was very useful for large construction projects.

While stone bridges are excellent for both travel and longevity, they left something to be desired for the price to build them, especially across a gap in the mountains, with no helpful rafts below. Lacking any other real building material, architects looked back at the old rope bridged that still crossed gaps too unimportant to warrant the expense of a stone one. They theorized that if there was some means of securing a bridge in the middle, it would be both much safer and be able to cross longer distances by effectively making two shorter bridges. Many early design for these bridges had small stone towers built up to meet the bridge in the middle, but these both defeated the idea of using little stone and were not stable at all. In an attempt to make them more stable, several guide ropes were attached to the top of the pillar, and ran to either side of the bridge. After one of these pillars collapsed, but left the top section upheld by ropes, the pillars were gotten rid of entirely in favor of a floating platform in the model of the bridge. While this was the end of the initial wave of innovation, over the next century this central platform transitioned into a proper Rope Suspension Bridge.

Barrel vaults and half-domes were all well and good, but architects could not manage to support a full dome made out of stone. In a measure to reduce the strain that would cause the design to break, it was made much taller, so the pressure was compact more the sheer. The rich who had wanted perfect domes looked at these Parabolic Domes, shrugged, and thought "good enough".

The cement the Arathee used had been improving slowly and steadily over the centuries, with various recipes featuring their own modifications (the majority of which had sand and volcanic ash in differing amounts) jealously guarded by architects. It was somewhat of a joke among moderately rich Arathee that soon you would have to replace the stones in the wall instead of the mortar. One architect, trying to cut corners, decided that the work of stone dressing wasn't worth it when compared to the strength of the Cement. With various sizes of rock mixed into the cement, it was poured into a mould of the wall inspired by the cassions used to build bridge pillars. This Concrete saw widespread adoption for the ease of making, compared to the painstaking shaping and laying of stone blocks.
