Gates of Reaper

The Gates of Reaper are a series of gates that seal off the overworld's underworld. There are four gates that you will encounter. While the first one's easy to get through, each gate gets harder. Essentially, by the last gate, you must prove you are dead.

Gate One - All you have to say here is that you wish to pass. Most of the time this will be allowed. If you're leaving, you must prove you are living, the hardest test to leave the underworld. Guarded by Armoured Zombies.

Gate Two - You must have a cold internal temperature to pass this gate. This makes it hard for warm-blooded who are still living to pass. If you're burning hot like some demons, he will allow you to pass. If you're leaving, you must be warm blooded or have circulation, this allows cold-blooded who are truly alive to leave. Guarded by steel-boned skeletons.

Gate Three - You must present a fatal wound or have a fatal condition within you in order to pass through this gate towards the underworld. To leave, you must have no fatal wounds (meaning healed enough at minimum) or conditions. Guarded by a succubus and an incubus.

Gate Four - You must prove that you are dead in order to pass this gate. Beyond this gate is the start of the underworld. You will find that the underworld is as eerie as it sounds. In order to leave the underworld, you must have approval to leave. Guarded by spike armoured shadow beings.
