The Outer World is a mirror dimension to our city, except everything is in ruins and monsters are flying around.
The whole area is destroyed, and left to destruction. There are a few buildings left standing, these have portals to areas where people are being held before the monsters or murders kill them. It is our job to stop them and change what happened so it does not appear in your dimension.

Outer World Monsters.
The monster will take any form just feed of the humans that get dragged in to the Outer World. They usually take the form of dark figures of someones past or a large dragon, but other types are known to appear.

The Sea of Data.
The sea of data is a large space of numberd and letters, this seems to take place of the rest of the world, if you come in contact with it part of you (the bit that touched it) it dissapear and be distributed in to the sea.

Spheres
The spheres are silver globes that try to absorb humans, when defeated, and use there memories to destroy other parts of the city, and turn those
memories in to shadows. There mission is to drain the sea of Data in to the real world and eat the data created.

Shadows.
Higher forms of monsters, they take the form of someone in a victims memories or the victem them selfs, the kill them when they have dought.
