MFW I haven't done any tech since the 900s

>Existing tech sheet<

The Radeti first brought home the secrets of wrought iron with them home from Onginia during the time of Telleth and Naotik's ascendancy. Other developments during this era saw the introduction of saddles and stirrups as efficient equestrians were a prime focus of the Naotik regime.

Adopted sometime during the Shattered Years, the Radeti use of coinage flourished as they quickly found it to be an essential component of trading with foreign powers.

In their attempts to fashion a single unified state from the disparate cities of Radet-Ashru, the Unone laid particular focus to technologies that would enable more rapid communications and transport of people, information and goods. One particularly important development was that of the caravansarai, which ensured that jauntee in service of the Unone could be the first to investigate and event of importance, and the first to return home with pertinent information.

Meanwhile the adoption of the oft-used and highly effective dhow proved a boon in transporting goods and information between Radet-Ashru and Noon.

Grandiose feats of architecture were meanwhile required to host the ever-growing 'Iyasu' - Creator's Day, a regular sporting festival hosted by the Unone. To this end Hashas notions of buttresses and half-sphere domes were 'borrowed' and the home-grown hippodromes and stadia developed to host events.
