'A grim ship sails forth on a black horizon, buffeted by waves of lost souls in anguish. The Hand of Justice is one who has heretofor escaped such a fate.'

Entering the next floor requires you to have earned at least six Abyssal Stars from the previous floor, as well as having cleared all three of the previous floor's chambers. Currently, there are only two types of challenges - one in which the player needs to clear the chamber in a set amount of time, and another in which a Ley Line Monolith must have a specific amount of health.
