Getting started
Enable one copy of Birthright — Ballads of Cerilia in your CK3 playset. The current release is v0.0.3 — Realms & Strongholds, released 18 October 2026, with declared CK3 compatibility 1.20.1.1. Fully restart CK3 when installing or switching versions; enable only one Birthright copy.
Create your first ruler
- Choose a human culture, Orog culture or Sidhelien culture. Read its guide to understand its traditions.
- Choose a faith that suits your ruler's personality and plans.
- For elven ancestry, choose Elven Blood in Ruler Designer: the ordinary entry starts at 25, while Elven Blood — Sidhelien starts at 100. Scores 1–25, 26–50 and 51–99 grant +20, +200 and +500 years of life expectancy; only 100 grants full disease immunity and immortality from age 18. Culture alone does not grant these benefits.
- If your ruler is blooded, check their derivation and strength. These decide their possible bloodpowers.
- Open Decisions to choose a class. This is permanent in normal play.
- Open the lifestyle window, pick a focus and earn perks. Right-click characters for targeted abilities; look in Decisions for abilities used on yourself.
Understand the main resources
| Resource or choice | What it means |
|---|---|
| Bloodline strength | How strong your divine inheritance is. It opens power tiers and raises RP capacity. |
| Regency Points (RP) | Power you can spend on special actions, bloodline growth and elite troops. |
| Bloodpower | An inherited gift, with permanent bonuses or an activated ability. |
| Class | Your lifelong training: Warrior, Divine, Merchant or Arcane. |
| Class experience | Progress toward perks in your chosen lifestyle. |
| Source holding | Arcane research site with study bonuses and eligible blooded-holder RP income. See Sources. |
| Ley Line / Arcane realm-spell access | Integration remains unfinished; a Source holding does not yet unlock realm casting. |
Guardians and wards
Each guardian can educate up to four wards at once, increased from the vanilla limit of two. Use the usual education and guardianship interactions to assign children; the education reminders also recognize the four-ward capacity.
Fully restart CK3 after installing the release. An existing save is sufficient for this change.
Before starting a long campaign
This is a developing mod, and a complete Cerilia map is not available yet. Use a separate campaign or a copy of a save while trying new features. A new game is the best starting point for culture, faith and portrait choices.
