This realm is where all the undead creatures reside, including ghosts, vampires, demons, and banshees. They can travel between our world and theirs through different means such as summoning, supernatural powers (like witches), or by using the decesso train, a unique subway that transports new souls to the Morte realm and allows any undead to visit the human world. This realm should not be confused with hell. Rather, it's a place for all the dead (and undead) to live in. However, there is a section in the realm that is reserved for those who deserve no sympathy. This section is guarded by a merciless punisher named Razru, and once souls are sent here, they do not return. The safety of the world is maintained by Dalvan. She is a half-angel, half-demon woman and a descendant of the original creator of this world. Her powers allow her to create life, but only to a limited extent. Alongside her, she created Lillium, a fake angel, to help her with her duties as a ruler. Creating life is not something she can do freely, as it requires taking something of equivalent value. The inhabitants of this place share a peaceful coexistence with the human world. Many aspects of human culture, including technology, hobbies, and food are shared within this world. Although none of the inhabitants are fully human, this place can be considered a parallel world that runs alongside the overworld. Creatures such as werewolves and human/beast hybrids belong in the living world but can have abilities related to the Mortem realm, allowing them to travel between.
