After the defeat of the Undead King by the adventurers of Midgard, the Royal Family of Geoborg started an investigation into the Niflheim area.
The investigation was conducted by the Queen Catherine D. Geoborg herself, and came to a conclusion that the Undead King was brought to our world by a terrible existence that was able to control it.
A witch with the name of Vanna, according to the legends she was a servant of Jormungandr the World Serpent during the Era when the gods created Midgard.
