Afanyu stones
In the first half of the 19th CSR a superhero warrior by the name of Tanira had emerged. His ability was to cause large objects to permanently hover at the altitude that matched his height.
His ability did not seem to be immediately useful for combat and he became an architect in what would later become the Upper Kingdom. He created large stones of different shapes that would then be used as a His hovering castles and towers became known in Darda and Northern Tarnaria.
Loodon began buying afanyu stones for the Temple of Gods of Mercy, bringing a fortune to Afanyu. By that time Tanira had already passed away and Afanyu was selling its limited supply of unused stones. Line Aylis stopped the construction of the Temple, but when Potus came to power, he resumed the construction.
Loodonians' pretext for the invasion of Afanyu was that they were denied more stones, due to the fact that Tanira was no longer alive to produce them, and the Upper Kingdom refused to take the stones out of its own buildings. This resulted in loodonian forces decimating Tanira's buildings in order to retrieve the stones. Frequently, the stones were also destroyed, which made them lose their hovering properties.
