House of the Dragon Season 3 is back on screens, and the timing could not be better for fans who prefer to rewrite Targaryen history themselves. A new community-made expansion for the A Game of Thrones overhaul mod in Crusader Kings III has just dropped, and it is packed with enough scripted content to keep ASOIAF fans busy for a long time.
What the Fire & Blood expansion actually brings
Steam user Refresco built this expansion specifically around two of the most consequential Targaryen rulers in Westerosi history: Aegon I (the Conqueror) and Jaehaerys I (the Conciliator). The mod adds over 400 scripted events split across both campaigns, pulling directly from George R.R. Martin'sFire & Blood source material.
The AGOT overhaul already lets you play as these rulers in a general sense. Here's the thing: this expansion goes several layers deeper, turning their reigns into fully fleshed-out narrative campaigns rather than sandbox starts with a famous name attached.
The Aegon I campaign events
For the Conquest side of things, players will encounter scripted events covering the major beats that Fire & Blood readers will recognize immediately:
- The Landing
- The founding of King's Landing
- The Burning of Harrenhal
- The Last Storm
- The Field of Fire
- The Submission of Oldtown
- The First Dornish War
- The death of Queen Rhaenys
- The Dragon's Wroth
- The Peace with Dorne
What makes this interesting is that these events are not locked rails. Players can steer outcomes in completely different directions. Aegon and his sister-wives could bring Dorne into the fold far earlier than canon, or broker an entirely different peace. The conquest plays out as a framework, not a fixed cutscene.
The Jaehaerys I campaign events
Jaehaerys gets comparable depth, with his long reign broken down into the personal and political crises that defined it:
- The regency
- Rogar Baratheon's defiance
- Jaehaerys and Alysanne's marriage
- The Doctrine of Exceptionalism
- Births and deaths of the royal children
- Aerea Targaryen and Balerion
- Rhaena Targaryen on Dragonstone
- Androw Farman's poisonings
- The theft of the three dragon eggs
- The construction of the Dragonpit
- The Shivers
What most players miss when they first pick up AGOT is just how much the mod relies on the base game's systems to make these stories feel alive. The scripted events here plug directly into CK3's relationship and succession mechanics, so Jaehaerys being a better father than he was in canon is a genuine gameplay possibility, not just a thought experiment.
Why this lands at exactly the right moment
The timing is not accidental. With House of the Dragon Season 3 airing now, interest in the Targaryen dynasty is at a peak. The official licensed game options for ASOIAF fans remain thin at best, which is exactly why the AGOT mod community keeps growing. This expansion represents exactly the kind of narrative depth that no official product has managed to deliver.
Refresco has confirmed that additional content is in development, covering other rulers active during the same period. The current release is more than enough to get going with, though.
For players who want to get the most out of either campaign, the Crusader Kings III strategy guides cover the core mechanics that underpin everything the AGOT mod builds on top of.
