📋 About This Mod
A mod that adds recognition of Illegitimate Children for AI Influence
Description
Illegitimate Children for AI Influence brings a natural consequence to the intimacy system introduced by the AI Influence mod. When your character — or NPC lords and ladies in close proximity — engage in intimate relationships outside of marriage, pregnancies can follow. Bastard children are born into the world with cultural surnames marking their status, and the affairs that produced them carry real consequences.
This mod is designed as a seamless extension of AI Influence rather than a standalone pregnancy system. Bastard events — conceptions, births, guardianship decisions, and affair revelations — are written directly into the affected NPCs' AI context files, so the characters involved will remember and respond to these events in future conversations.
Main Features
-
[]Player intimacy → pregnancy — Intimate interactions through AI Influence can result in illegitimate pregnancies, using AI Influence's own conception chance. The NPC's AI context is updated so they are aware of the pregnancy and can speak to it naturally.[/]
[]NPC proximity conceptions — Optionally, NPC lords and ladies sharing a settlement or army may conceive illegitimate children based on their traits, honor, and relationship with each other. Runs daily in the background.[/]
[]Cultural bastard surnames — Bastard children are given a regional surname at birth based on their culture: Snow (Sturgia), Waters (Empire), Rivers (Battania), Hill (Vlandia), Grass (Khuzait), Sand (Aserai).[/]
[]Configurable birth system — Set minimum and maximum gestation time, stillbirth chance, and labor death chance independently via MCM.[/]
[]Consequences — When a married NPC gives birth to a bastard, the affair may be revealed at birth, triggering relation penalties against the player with the deceived spouse and the clan leader. A configurable chance allows the affair to be kept secret instead, with the child quietly legitimized.[/]
[]Legitimization — Acknowledge a bastard child through direct conversation with them as an adult. They are added to your clan as a Lord or Lady and their surname is removed. Bastards also legitimize automatically on marriage or when inheriting clan leadership.[/]
[]Notable bastards become wanderers — Bastards born to notables (who have no clan) grow up as wanderers, findable in taverns across Calradia.[/]
[]Full AI context integration — Conceptions, births, guardianship, and affair revelations are all written to the relevant NPCs' AI Influence context files. NPCs remember these events and factor them into conversations.[/]
[]MCM settings — All major systems are individually toggleable and tunable without requiring a game restart.[/]
