Snowball Earth

Snowball Earth is the residence of Cocytus.

Background
It is located on the Fifth Floor of the Great Tomb of Nazarick

Layout
Cocytus's home resembles an overturned vespiary; surrounded by six floating pillars of ice, where reside the Frost Virgins. The walls, ceiling, and furniture seemed to be made out of ice. This was probably an artistic decision. Aside from that, it wasn't much different from a regular home. However, it was big enough to include a conference room. It was big enough that Cocytus could swing his swords without a problem anywhere in the interior.

Trivia

 * Cocytus's home was designed for fighting that takes place indoors.
