This is rather simple, actually. The entire Otherworld is in a frozen state (caused by Qua-Jin). All spirits entering the Otherworld would join in on this suspended state. If your character dies, you will need to be in touch with me about how to go about the Otherworld. If you wish to travel to the Otherworld, or Underworld for that matter, you have to be in touch with me about what/why you are. You can only normally access the Underworld by death in the Otherworld.
