1. Square-rigged sails, 2. Masts, 3. Spars: The Terrock people have long been fans of relaxing on the beaches of the Great Southern Sea, feeling the cool ocean wind and watching the palm trees bob in said wind. This routine of calming relaxation was, on occasion, interrupted by savage windstorms far stronger than the beaches' usual light breeze. The most devastating of these unpleasant meteorological events could even tear the mighty palm trees from their roots, and propel them through the air by their long, wide palm leaves.

Since time immemorial, the Terrock have viewed these spats of inclement weather as nothing more than nuisances of the highest calibre. That is, until a Terrock oarsman was rudely interrupted from his relaxation by one of these windstorms. While running to take shelter in his sturdy mudbrick home, he caught sight of one of the above-mentioned palm trees flying through the air. At this moment, he made a connection. As an oarsman, he was acutely aware of how bone-crushingly exhausting and mind-numbingly tedious rowing was. Yet, such exhaustion and tedium was necessary to make boats move. Unless, of course, boats could be made to move on their own.

Although the intensely strong winds capable of uprooting a palm tree would surely also be capable of capsizing a boat, even the lightest of winds make the leaves of a palm tree move around. Realizing that he had conceived of a potentially massive reduction in his workload, the next morning he approached several of the local boatwrights with his cunning plan. Without fail, they all laughed at his ridiculous notion of propelling boats through the use of palm leaves, of all things. However, he did manage to convince one to attempt the construction of such a vessel, because building a nonsensical contraption is better than building yet another boring old canoe.

Although the first prototypes ended in unmitigated failure, either through instantly capsizing, or an inability to harvest any propulsion from the wind at all, a working vessel was eventually constructed, by affixing a braided sheet of palm leaves to a tall, vertically-placed log and a horizontal crossbeam, attached upright in the middle of a large canoe. Although unreliable and difficult to control, the production of a vessel that successfully harnessed the power of the wind stunned the naysayers into full-fledged support for the concept. Several iterative wind-boat models were constructed in rapid succession, each slightly more reliable and controllable than the last, until a reasonably useful vessel was created. Intra-cultural raids by such majestic seagoing boats spread the design throughout Terrock lands.

4, Uniremes: Over the centuries, the various wind-propelled boat designs used by the Terrock eventually coalesced into the unireme, a vessel featuring a crew of anywhere between two- to four-dozen oarsmen, depending on the specific vessel's size, and one or two masted square-sails as its twin propulsion methods. Although somewhat uncommon, as the construction of such a majestic boat took a considerable sum of resources and manpower, these vessels are slowly becoming the mainstay of Terrock fleets based out of larger towns and settlements.

5. Cold-working: Terrock adventurers have recently stumbled upon lumps of shiny, reddish-orange pseudo-rocks lying around. Some Terrock sages and stone-shapers found that this new pseudo-stone was unusually soft, allowing it be crafted into jewlery and other decorative doodads, but unsuitable for replacing the use of more traditional stones in tools and architecture. However, the newfound class of Terrock metal-shapers found when pieces of this reddish-orange pseudo-stone are deformed repeatedly, they begin to lose their distinctive softness, which was initially dismissed as an inconvenient flaw of the material. However, some of the cleverer of the metal-shapers thought the opposite, and endeavoured to work pieces of the reddish-orange pseudo-stone repeatedly in an intentional fashion, to alleviate the material's inadequacy for use as the business end of a tool. These metal-shapers were successful in their endeavours, and now copper tools are becoming commonplace among Terrock farmers, fishermen, masons, carpenters, and, of course, warriors.

Diffusive

The expansion of peaceful relations with their neighbours has yielded a wealth of knowledge to the Terrock people. Explorers from the Southern islands, calling themselves Einah, have introduced the Terrock to tasty barley-based bread products, prompting the Terrock to begin cultivating their own local wild barley. Traders from the Heyoo on the Western Rorroch river have introduced the Terrock to the concept of domesticated cattle, and the practice of curdling milk. From the Geddockoska to the North, the use of several naturally-occurring and synthesized substances has adopted, as well as the process of treating rawhide with urine.

1. Barley domestication: Ina

2. Taurine cattle domestication, 3. Curd: Hjeu

4. Tannins, 5. Lye, 6. Quicklime, 7. Urine-treated rawhide: Gedokosza
