Hey adslahnit! 
The spirit realm derives from the mortal realm. Lawful evil spirits from your world travel to afterlife in the Nine Hells.
When cultures meet there is a sharing of information, including religion.
e.g. In the court of Genghis Khan virtually every religion was catered for.
The 'meeting' of the Hells in this example, is merely a metaphor of this coming together of religions/ethics.

Adslahnit said:How exactly does that happen? Let's say Planet A sends a magical spaceship that lands on Planet B, and the explorers meet the natives of the new planet. How does Hell A "meet up" with Hell B in that case?
