All is well. Absolute peace throughout the Void between innernations. Peace with nations, or obliviousness towards them, from the outside of the Void is also in effect.
All is well. Slight tension between nations ruling the Void. Tension causes small anomalies in the Void, and throughout nearby universes. Awareness to extra-Voidal nations is current.
All Imperiums, Democratic Unions, etc. within the Void become militarized, closing their borders. The Voidmasters' self-tension causes ripples throughout the Void and nearby universes. Void Portals are commonplace. Interaction with extra-Voidal Nations causes tension to build up outside of the Void.
Extreme militarization throughout the Void. Minor factions are warring. Tension causes the barrier between the Void and other universes to thin and weaken extremely. Void Portals become natural occurrences. Interaction with extra-Voidal nations is starting to increase in tension.
War throughout the Void. Tension causes the borders between the Void and other universes to become almost nonexistent. Void Portals no longer needed to transport into the Void; rather, powerful FTL is only needed. Minor factions begin warring with the "outside" worlds.
War throughout the Void. Tension destroys borders between the Void and other Universes, causing all universes connected with the Void to be indirectly connected. Multiversial War.
The Voidmasters have awoken from their slumber due to the tension. All Void Inhabitants are at war in some form or another. Nearby universes begin getting pulled into the Void as if it's one big Void Portal. Collapse of the Voidcore possible, and lethal to those closest to it.
