Glacier Dungeon Arc

Ragnarok's thirteenth arc begins when an uninvited guest turns up at Suho's home. He is Thomas Andre, the famed American S-Rank Hunter, and he has come to enlist help for a raid on the dangerous Glacier Dungeon. Prophecy, Thomas explains, binds the mission's success to Suho specifically. As his sweetener, the legend hints that buried inside this frozen place lies a lead on Cha Hae-In, the mother Suho lost. That hope is enough to win his agreement, yet the icy depths hold something other than the tender reunion he pictures.

Reaching the dungeon by way of Nauru Island, the party threads through a village of Ice Elves, then the Forest of Echoes, and finally the Snow Folk's Sanctuary. An Ice Dragon interrupts the duo of Suho and Cha Hae-In before their fight resolves, yet when Thomas joins them the trio manages to put down the Apostle of Itarim. Frost-touched monsters crowd every chamber: Kobolds and Trolls made of ice, Ice Spirits, and the Elves who guard the place. Alongside the leads, the cast features Derek Johnson, Sirka, Kaisel, and Sillad.

Suho departs stronger and better connected. From the Forest of Echoes he carries off its Spring Water, and the formula for brewing Holy Water of Life comes with it; he also picks up the Frigid Blizzard skill. This arc debuts Sirka, who inherits Sillad's mantle and takes up his old trident, the Ice Tree Spear. The deepest payoff is personal, as Suho frees his mother from her captivity within the dungeon, while Thomas Andre's memories of the prior timeline come flooding back. The story then rolls onward into the Jisan Prison Break Arc.
