Amadeus Von Glashausen

"Ugh, that smell. I hate this medieval shithole." 
-Amadeus, about Arkon
Amadeus Von Glashausen, formerly known as K'jjah Aesja, is an interdimensional adventurer, arms manufacturer, and prince, as well as an inventor for Johann Industries. He is both a kaaz and a titan, making him semi-immortal. He is widely considered to be a top inventor in his field, specializing in arms manufacturing. Amadeus is the inventor of the dynamo core, a mysterious contraption that bridges to gaps between science and magic, and allows for the creation of automata and other advance forms of magitechnology. 
Amadeus is also one of the few adventurers capable of traveling between worlds, having gained this ability thanks to an anomalous compass. The compass's origins are shrouded in mystery, but barring the fact that it is clearly from outside of Annaad, little is known about it. 
Amadeus was also born as K'jjah Aesja, the crown prince of the Kingdom of Artaikaro's ruling Aesja Dynasty. When he was six, Artaikaro was invaded by the neighboring Kingdom of Jakara, and during the Fall of Zandalay, he used the magic compass to flee to the Brass Republic. There, he would shed himself of his old identity, and take up his current name, Amadeus von Glashausen, as well as gain his robotic body. 
Amadeus's first return to Arkon came during the mid-11th era, sixty years after his disappearance. Originally sent on a magiological research mission by Johann Industries, he lost his compass in transit, and ended up stranded in the Eastern Ichovian Empire, where he was found by a party of adventurers. Begrudgingly, he allowed them to befriend him, and take him with them on their adventures. However, while lost in a dungeon, he had falling out with them, and broke off from the group. Following this, he wandered the world on his own, until he found his compass in his homeland. There, he came to terms with his family and history, and helped them fight for Artaikaro's independence from Jakara. Though granted the title of Count of Karo by his sister the queen, he would refuse, in favor of returning to the Brass Republic. 
His second visit came during the late 11th era, when he broke into the vault-library of Aln'chalgrae, searching for information regarding a plague that had stricken the Brass Republic. There, he commissioned the aid of a party of adventurers on the payroll of Angra the Betrayer to break him into the lower sections of the library. Following their success, he began providing them his weapons manufacturing and fast-travel services, until they returned with a cure. 
During the Convergence, he was a key figure in stabilizing the breaches between the Brass Republic and the conjoined world of Earth and Arkon, and following that, he began researching interdimensional travel. His current project is about how third-party worlds such as the Brass Republic and the Crown Sepulcher could be act as potential bridges crossing the divide between worlds. Though his lab is in the the Glass District of the Brass Republic, he also has several branches in other realities, such as in Arkon's Sephirot.
