After leaving the tower, Bartlett's journey through the Realm of Darkness was gradually coming to an end.
He granted the White Bone Naga Sisters their freedom (actually, that just meant he told them they could go anywhere and didn't have to follow him), and then continued searching for quest items with the Little Ghost.
Carrot tirelessly ran through the darkness, its burning green ghost fire trailed behind it in a long, thin line due to its high-speed movement.
After an unknown length of time, Bartlett, under the wide search and guidance of the Constructed Entity Raven, encountered another rare undead creature from the task list - the Monster Hunter.
