Insanity

A commander with (X) amount of Insanity (formatted as "Insane (X)") will have an X% chance before the start of each turn to refuse accepting commands from the player this turn and perform some random action instead. Their little square will be colored red instead of the usual black. They may:

• Patrol
• Site-Search (or at least attempt to)
• Enter a local Site (or at least attempt to)
• Research (or at least attempt to)
• Preach (or at least attempt to)
• Call for their God (or at least attempt to)
• Hide
• Hunt for Blood Slaves
• Claim the local Throne (or at least attempt to)
• Become a Prophet somehow, even if you already have one (LA R'lyeh only)
• Waste the month searching for "signs" (no effect)
• Waste the month agonizing over a star that's not a star (no effect)
• Give in to the Madness (giving the province to LA R'lyeh, if the nut's is high enough and no Dominion is present)
  • If there is Dominion present, it's weakened by 1 candle if the insanity is successful (or strengthened for LA R'lyeh)

They have a 50% chance to do one of the stupid useless things, and a more-than-50% chance to be useless overall (unless they're Mages in a special spot). Thankfully, provinces can't be given to factions that aren't in the game.

You generally don't want to rely on Insane commanders, and you certainly don't want to render your Commanders Insane if you don't have to. The following give Insanity:

• Holding the Dimensional Rod (+1 per month)
• Lingering in Late Age R'lyeh's tainted Dominion (+1d(Dominion) DRN per month)
• Using the Void Gate ((65/Void Sanity)% chance, +2d(65/Void Sanity) DRN)
• Entering The Void (50-100% chance (divided by Void Sanity) of +1d6 DRN per month)
• Chugging Mercury to de-age yourself with Internal Alchemy (typically +5; less if you're at or above 50, but never zero)
• Having The Gift of Kurgi equipped (+10 upon equipping, then +2 per month)

A Commander with a Shattered Soul (X) has a more dangerous form of Insanity, typically brought about by being in Hell for too long. They have an X% chance of refusing input and doing something stupid, like Insane Commanders, but their list of actions is generally far more destructive. They might:

• Pillage
• Destroy a local Temple
• Research (or at least attempt to)
• Preach (or at least attempt to)
• Call for their God (or at least attempt to)
• Site-Search (or at least attempt to)
• Raise Ghouls from the local populace (exempting them from taxes)
• Give in to Despair (giving the province to MA Ermor, if the poor guy's is high enough and no Dominion is present)
  • If there is Dominion present, it's weakened by 1 candle if the insanity is successful (or strengthened for MA Ermor)
• Do something scary but ineffectual (30% chance)

Nothing increases your Soul-Shattered-ness, thank gosh, at least within the scope of the game.

Void Sanity (X) divides your Commander's chance of going insane for a month by X; for example, a guy with the maximum amount of Insanity (100) and the maximum amount of Void Sanity (20) has only a 5% chance of losing it each month. MA Atlantis has a Hero with Void Sanity (100), so he has only a 1% chance to lose it in even the worst scenario. Void Sanity also reduces insanity gain from certain sources, as listed above, and having any amount protects against some rarer mental effects.

For the sake of the calculations that divide stuff by Void Sanity, everyone has at least Void Sanity (1); otherwise, everyone who doesn't have the Void Sanity icon doesn't have Void Sanity.
