—The Abysskeeper's usual greeting to Byleth.
The nameless abysskeeper is a non-playable character from Fire Emblem: Three Houses.
The Abysskeeper stands guard at the entrance to Abyss, the network of tunnels that run underneath Garreg Mach Monastery. He proudly reports on the going ons of Abyss, as well as his own personal frustrations. He used to live in Derdriu before heading to the Abyss for unknown reasons.
The most prominent of his frustrations lie with Mr. Backup, a man who was sent by Seteth to help the abysskeeper with his duty. Despite his initial reservations about the man, the abysskeeper comes to care for him, and admits that he feels lonely when Mr. Backup returns to the surface.
He returns to his post after the five-year timeskip without Mr. Backup. After spending some time searching for the man, the abysskeeper learns that Mr. Backup died in the war. He meets Mr. Backup's big sister in the process, and the two end up engaged.
The abysskeeper is very boastful about his job as the abysskeeper, believing that he's the only one who can do what he does. This changes as his relationship with Mr. Backup deepens, and the abysskeeper comes to care about more than just his job.
