The Void is one of three alternative planes that can be travelled to, along with Inferno and Kokytos. It is the realm of the otherworldly creatures of R'lyeh and those exposed to it are likely to become permanently insane should they return at all.

Unlike the other two planes, there is no direct method to send an opponent to the Void.

• Certain random events may banish commanders to the Void
• Outcomes from the R'lyeh Void Gate can result in sending the summoner to the Void
• Being teleported by the spells Returning, Vortex of Returning, or Ritual of Returning has a 7% chance to send a recipient to the Void instead of their capital province. The Ring of Returning seems to not carry this risk.
• Temporarily, when casting or being the target of Dreams of R'lyeh

Being in the Void is hazardous to anyone who makes it there. Each turn, the following things happen ¹⁾

• Any non-commanders who are in the Void invariably die without any chance of survival.
• All units in the Void have a 100% chance to gain 1d6 (exploding) Insanity. This chance is divided by the unit's Void Sanity value, if any.
• There is a 15% chance that the commander comes under attack by various void creatures. Creatures without Void Sanity fight under the effects of Dimension Overload.

• Irrespective of being attacked or not, the chance of returning is rolled next. This is 5% plus any void returning modifiers (though sources of these are not known).
• Upon returning, there is a 30% chance of gaining +1 astral and +2d50 (exploding) insanity. This cannot occur for units with 4 or higher already.
• When returning, there is a 10% + (20% per astral level) to return in a province belonging to the owner of the lost unit. If not successful, a province is picked at random. In either case, the returning unit immediately drowns if appropriate, and then attacks the province if it is hostile.
