Suikoden
"Do you have business in my vault?"

- Rock Rock was an employee of Lepant hired to guard and maintain the vault of the Lepant family mansion in Kouan. However, he was sympathetic to the liberation movement and joined the Toran Liberation Army shortly before his master. At Toran Castle, Rock was placed in charge of the army's vaults.

Rock seemed to have an interest in large vaults, which served him well after the war when Rock was tasked with designing a new giant safe for the dwarves of the Great Forest region, as their current vaults had been infiltrated twice throughout the Gate Rune War.
