I love the idea of the Void Gate. I really and truly want it to be moddable, and to be able to add void critters of my own design. I think it could be as significant a factor to base a nation around something like a Void Gate, as to base one around the ability to cast certain spells or forge items.

Suppose you had a nation that could access Tartarus, or Cocytos, One of the elemental realms, or the Japanese underworld? Maybe a gate to the far future or the far past, from which can be drawn dinosaurs or mechanical beings.
