[Synchronization]—the name of the Technique that bewildered Gorgophone in Basil's past life. This was the Technique that Gorgophone couldn't believe a human could ever master, but Basil managed to master.
What was [Synchronization]?
Essentially, [Synchronization] was a state where a Swordmaster was so close to his sword, it developed a consciousness, which people had come to call Sword Soul.
Sword Soul was originally a part of the Swordmaster's soul that became independent, however didn't do any harm to the Swordmaster, and instead greatly aided him in battles.
Sword Soul brought many benefits to the Swordmaster, but it still needed to be cultivated so it could keep growing stronger. [Synchronization] was the way to nurture the Sword Soul.
In Basil's case, thanks to his genius, he could perform [Synchronization] with Vagus, which, at that time, had contained the half fragment of Asia's soul that had been cursed to be forever bound to Vagus.
