Inheritable Relations (IR) – Rework

Fan-maintained rework for CK3 1.19.*

Some bonds outlive the dead.

This is an early community test build of Inheritable Relations for current CK3 versions. The goal is simple: keep the original idea alive and make succession feel less like a complete social reset.

Because this mod spans succession, inheritance chains and multiple generations of gameplay, it relies heavily on community feedback, bug reports, screenshots and error logs.

Original mod & concept: Big Uncle
Full credit for the original concept, systems and foundation goes to Big Uncle and the original Inheritable Relations / Unfinished Business work.

1.18 continuous work: Clem
Special thanks to Clem for keeping the mod available for CK3 1.18.

Rework & maintenance: Elchman69
This rework updates and maintains the core systems for current CK3 versions.

I do not claim ownership of the original mod, name, concept or design.
If the original author or previous maintainers want this version removed, renamed, credited differently or changed, I will respect that request.

Inheritable Relations allows heirs to inherit traces of their predecessor’s most important relationships.

Current focus:

• friends and best friends
• rivals and nemeses
• positive and negative 10-year opinion memories
• potential future friendships and rivalries
• original-style primary-heir focused inheritance
• game rule support for inherited best-friend relationships

This rework is intentionally conservative.

It is meant to create strong roleplay moments without turning long campaigns into a map-wide relationship web.

Current safeguards:

• no title-revocation grudges
• no dynasty-wide relationship spam
• no uncontrolled maternal-line grudge spread
• no permanent revenge casus belli
• no global yearly pulse checks
• Forgiving heirs do not inherit hostile grudges

Recommended order when using the companion reworks:

• Social Relations Expanded (SRE) – Rework
• Inheritable Relations (IR) – Rework
• Rescue & Vengeance (R&V) – Rework

This mod also works standalone.

Should be compatible with most mods that do not overwrite the same succession / relationship inheritance logic.

This mod is not achievement compatible.

• English
• German

• more community testing against the original behavior
• optional SRE support
• optional R&V support for strictly time-limited Fresh Blood Debt mechanics
• more polish, balance and performance safety

Succession should not erase every meaningful bond in CK3.

A father’s closest friend should not become a complete stranger overnight.
A bitter rival should not always vanish from history the moment one ruler dies.
