Goblin Slayer, Vol. 8 (light novel‪)‬

An urgent council meeting has been convened at the royal capital, and the archbishop of the Supreme God, Sword Maiden, requests that Goblin Slayer and his party escort her there. Rumor has it that packs of wolf-mounted goblin riders prowl the route, and no other adventurer is better suited for such a job than Goblin Slayer himself.
Little do they realize there have bene dark whispers at their destination of a fiery stone that has fallen from the heavens upon the holy mount...
Whether by Fate or by Chance, this ill omen comes just as the adventurers arrive and ends up leading them to the deepest labyrinth, the darkest abyss: the Dungeon of the Dead.
