Abilities
So far, it was revealed that Vesture is a highly skilled martial artist and swordsman. Vesture himself has developed a stronger technique that surpassed the Sixfold Slash of Light, however, he was unable to utilize it to its full potential due to his advanced age, which he then taught it to Gazef Stronoff.

Gazef Stronoff
If Gazef hadn't met the retired adventurer, his fate would have been to become a mercenary. It was Vesture who dragged him into his school and taught him all the skills of the sword, leading him to become the Kingdom's strongest warrior.
