| - The development of the Uron-Tashra is closely related to the development of Kartazian energy production. Everybody knows that the first Uron Tashra, called "Mahontes" was developed on 1583 by a couple of Zaitsan engineers named Mykan Ufron and Eleya Tashra. However, their discovery was only possible because of the technological framework left by Kryss Erezgath and his famed clockworks. Erezgath's car, built on 1553, was moved by a small metal cylinder which contained an enchanted jewel that continually created air. The pressure of the air would move the car forward. That was the first magically powered energy tool, called a "Constant Pressure Device". The energy output of a CPD was useful in but a handful of applications and nothing more. On 1557, a different method for creating power was devised: a different metal cylinder enchanted to continually create water and turn it into steam, named "Unending Steam Cylinder". The USC produces about ten times more output than a CPD, but still not enough for any commercial use. On 1564, a group of mages created a "Continual Clockwork", which would move without stop based on the "Apportation" spell. A new development which already allowed some modest use of magic in technology, but which was barred from large scale use due to the high cost that the enchantments would require. 1570 saw the birth of the Mana Engines, a device which would use all of the previous three's technologies to constantly produce power by draining local mana. A significant advance. However, development of further advances on the Mana Engine was halted after a group of mages was found to have developed a "Blood Motor", which would generate considerable power draining it from the lives of captive people. These mages caused great turmoil in magical society as they nearly toppled Zaitsan government with their magical fighting machines. Mykan Ufron and Eleya Tashra were not only excellent engineers, but most importantly the mages who developed what would become the main source of energy of Kartazia, and the single invention that changed the face of the continent: the "perpetual mobile keys". A PMK is a small metal key enchanted with "Lend Power" and "Power 1" enchantments. A simple enough feat for a tremendous output of energy: 360 kwh. It was the PMKs that were the great secret behind the development of the Uron-Tashra. Nowadays, mostly all engines in Kartazia are moved by a PMK. The steam boilers used on 1581 to move the first commercial trains are almost all retired. The PMKs offer a clean energy which requires no fuel, takes no space, and can be stored in a pocket. No other source of energy comes close to competing with that. A PMK usually costs $50000 for any individual which wants to acquire it. Mages can get a discount in buying them and can get one for about $40000. However, their high price is not enough to prevent most people from taking large debts in order to get one. Ownership of a PMK makes life much easier for a Kartazian, and opens up great possibilities as it allows one to purchase a large option of mechanical devices that require the keys: from cars to airjets to house refrigerators. The wealthy have PMKs fashioned to work only at their hands, or the hands of their descendants, for a great increase in price. There are also more powerful PMKs, yielding 720kwh, or even 1440kwh, but very few mechanisms have need of such power output.
