Hero's Guild Trilogy:

After the defeat of Satan's plans to destroy Earth failed, Shadowstone and his friends decide to set up an organization that draws the best talent from Existence to fight Satan and the forces of evil. This organization is called the Hero's Guild. Members are recruited by other, long standing members or the Directors, trained and equipped, then sent to a conflict that they are best suited to handle in whichever  universe the conflict has arisen.

Using the hyperspace lense technology, Shadowstone and the other Guild  Directors place a huge planetoid in hyperspace between the  seven existing Universes, hollow it out and equip it. This then becomes the main base of operations for the Hero's Guild.
