The dungeon that appeared on an island somewhere in the middle of the vast Sea has been officially named “Niflheim.” Monster attributes are to be catalogued at a later date.

Ikanbam (Related Story)
Description: A whale that spews curses. It shrieks at the hour when the full moon rides highest. Whoever hears this shriek suffers headaches for three days and, in the end, takes their own life.
Attributes: Sound, Water
Appearance: Its body is large enough to be seen even from far away. It is black, hard to spot at night. It takes the form of a whale.
Weakness: If you let out or make a sound louder than the shriek the whale spews, you can avoid the curse. Beyond that, if you hunt it when there is no full moon and the whale is not shrieking, it is no different from an ordinary whale.
Caution: Take care not to hear the whale's shriek directly. It is said that all who heard the shriek suffered their own distinct headaches and, on the night the third day passed, took their own lives.
