An underworld once lorded over by Hades. A conduit connected through a canal filled with oily water can be found underneath Kalpa 1, but it has since been sealed by Vulcan. Styx still functions as a realm of the dead, even with its host having been slain.
The waters of Styx cause total amnesia as they separate the spirit and soul from one another, although the latter function does not technically occur if the individual in Styx is in fact alive. Styx cannot be safely traveled or forded without paying Charlie two gold coins for passage on his boat. Conditions in Styx are unknown at this time as the place still functions as an afterlife of sorts even though no one is apparently in charge at the time.
