Lilies by the Brook

Ellie and her brother Corbin are dungeon crawlers. Their job is to clear out monsters, ghosts, werewolves, etc. in any nearby dungeons while securing all items they find. They heard rumors of an artifact known as the Totem of Undying and the rumors sounded too good to be true. Now they must make their way through one of the most dangerous dungeons they have ever encountered. Little do they know that one of them won't see the dawn of day again.
