Who was Havek Sasamil? Back in the Sasamil Empire, Rean participated in a competition on formations that involved the main powers of the entire empire. It was there that he met Qia, as well as Havek. After the events that unfolded, Rean ended up inviting Havek to help with the development of the communication system. Havek, who had seen the Circuitry Runes for the first time, obviously accepted.
Havek was truly a genius in formations, but his genius didn't stop there. He also knew a lot about talismans and was obviously a genius in cultivation. Last but not least, he had access to all the cultivation techniques in Sasamil Empire. When one put it all together, neither Rean nor Roan found it hard to believe that Havek developed that cultivation technique for Magali.
