Do demons from similar planes try to recreate their home in the abyss and make cities based on that? I know the city Tom was in had many elements from his Earth and he was likely from a central reality as he recognized elements of cities in his world in the demonic city. I ask this as demons are all shunted to the abyss. This means that demons will have variances based in part on where they originate and where their summoners originate. I’m curious as this means the abyss is likely populated by demons from countless worlds and realities. It also makes the boom gate much more practical as it would allow for quick transport between the extremely distant cities as the abyss is in all likely hood a plane that is near many other planes.
Demons will thus likely group with other demons from a similar world to share in past culture and due to similar idiosyncrasies that might exist across a single world. They will also likely take interest in their summoners world. Wizards from other worlds will have difficulty finding the name of a demon created outside their plane. Those from their summoners plane will be the people they most often interact with, and thus be the ones with whom they will have to be indentured to as names do not travel as often.
