Causes of imprisonment
Arrest by liege
Lieges can attempt to arrest any character they control. This has a variable chance of success depending on respective Intrigue scores, and will incur tyranny if attempted without cause. Unsuccessful imprisonment of an unlanded courtier or indirect vassal will cause them to flee the realm and abdicate titles to their heir if applicable, while unsuccessful imprisonment of a direct vassal will spark a rebellion with the Overthrow Ruler casus belli.
Valid causes for imprisonment are:
- Plot leader
- Plot participant who refused the liege's demand to leave it
- Dishonorable actions. Cuckolding the liege (typically through Seduction) qualifies, as does being caught at murder.
- Character has been excommunicated
- Refused liege's demand to settle an internal war, under Late Feudal Administration or higher. (Requires Conclave and The Reaper's Due.)
- Muslims only:
If as a liege, you have a direct vassal whom you consider too powerful or otherwise too threatening to your rule, it can be to your benefit to fail to imprison him (usually after your spymaster has caught him/her plotting against some random NPC). It's usually unlikely he will succeed in his revolt, and the revolt will give you cause for title revocation.
Other causes of imprisonment
- Capture commander in battle
- Capture courtier in siege
- Rebelled against liege and lost the war
- Various random events
- Intrigue focus spying event
- Hermetic society sabotage event
- Demon Worshippers society abduction event
Effects of imprisonment
Characters in prison:
- require a regent and can have weak claims pressed against them
- cannot create, join, or continue to be members of factions
- cannot declare war
- do not contribute to a dynasty's decadence
Characters imprisoned by their liege:
- cannot refuse title revocation (and the captor does not have to wait for an answer)
- cannot refuse vassal retraction
Characters imprisoned by their direct vassal:
- cannot refuse faction demands
If a ruler's close relative is imprisoned, that ruler cannot declare war on his relative's captor.
If the leader of a war is imprisoned by the other side, the captor can enforce demands on the prisoner.
If a woman gives birth in prison, the infant remains in prison with her.
Actions available to captors
- See also: diplomatic actions available to captors
Prisoners are usually held in dungeon cells, but can be moved at any time between:
- Oubliette: -20 diplomacy, -2 health, no fertility
- Dungeon Cell: -10 diplomacy, -1 health, no fertility
- House arrest: -5 diplomacy
Rulers left in dungeon cells will eventually trigger an event requesting nicer conditions. In this event, you can change their conditions or release them for a favor.
Actions that kill prisoners
- Based on religion:
- Aztec: Sacrifice
- Zun: Have judged by the sun. This usually kills said prisoner but other outcomes are also possible.
- With The Reaper's Due:
Some rulers can also hold festivals that include prisoner sacrifice:
- Germanic pagans: Blot
- Most other pagans: Ancestor Worship
- Some Hindus: Kali Puja
Actions that release prisoners
- Banish vassal: they are forced to abdicate all titles. Must be your direct vassal.
- Banish courtier: you seize their wealth, and they move to another court. You must be their liege in addition to their captor (host). Cannot banish your spouse.
- Ransom: generally, AI rulers will pay to ransom themselves, spouses, close kin, or courtiers rich enough to reimburse the ransom. They may pay ransom for other dynasty members they like enough (moving these prisoners to house arrest helps). The AI will often refuse to grant ransom to characters who hold claims on their titles.
- Release: +3 realm opinion per rank, for 30 months, when releasing a ruler. Does not stack when releasing multiple vassals. 5 piety if prisoner is of same religion.
- Demand religious conversion: Must be your courtier or direct vassal.
- Castrate the prisoner: Requires Byzantine culture group. Eunuch disinherits characters and prevents them marrying or being granted titles.
- Blind the prisoner: Requires Byzantine culture group.
- Force the prisoner to become their concubine
- With The Reaper's Due:
- Bad Poetry: Requires Poet .
- Humiliate: Prisoner gets Publicly Humiliated for 10 years (-25 general opinion, -2 monthly prestige)
- Recruit courtier: Must be an unmarried capable adult, and not parent/child/lover/friend of their liege. Opinion difference at least -25. Note that you *can* send gifts to prisoners to increase their opinion.
Prisoners will also be released if:
- The captor chooses to sign a peace treaty in a war to which the prisoner contributes warscore (100% for ruler, 50% for spouse or heir, 5% for ruler's other children).
- The captor becomes unlanded.
