The modding community for Mount & Blade II: Bannerlord has reached full maturity in 2026. Developers have constructed entirely new universes within the Bannerlord engine. From fantasy realms filled with wizards and dragons to highly researched historical overhauls, these total conversion mods offer massive, completely free game experiences.
Top 5 Featured Conversion Mods
1. Realm of Thrones (Game of Thrones)
Theme: High Fantasy / Westeros & Essos.
This mod brings George R.R. Martin's A Song of Ice and Fire into Bannerlord. It includes a massive custom map representing Westeros and parts of Essos, dozens of custom factions (Stark, Lannister, Targaryen), hundreds of unique armor sets, and fully interactive dragons that burn entire infantry armies on the battlefield.
2. The Old Realms (Warhammer Fantasy)
Theme: Dark Fantasy / Warhammer universe.
A highly polished total conversion mod that injects Warhammer lore into the game. It features completely custom game mechanics, including a fully functional spell-casting system, gunpowder musket troops, artillery, vampires, giants, and custom necromancy spell trees.
3. Eagle Rising (Roman Empire Era)
Theme: Historical Overhaul / Early Imperial Rome.
Perfect for history enthusiasts. It replaces the low-fantasy Calradian factions with early Imperial Rome and its regional rivals. The detail on gladius swords, legionary shields, and centurion helmets is outstanding. It is frequently paired with European map mods for full historical campaigns.
4. Kingdoms of Arda (Lord of the Rings)
Theme: High Fantasy / Middle-earth.
A massive, ongoing total conversion mod bringing J.R.R. Tolkien's universe to Bannerlord. It introduces custom races (elves, orcs, dwarves) with unique skeletons and animations, Middle-earth kingdoms (Gondor, Rohan, Mordor), and famous historical battles.
5. Shokuhō (Feudal Japan)
Theme: Historical / Sengoku Jidai.
Shokuhō transports players to late 16th-century feudal Japan. It features custom samurai clans, katanas, yumi bows, matchlock arquebus rifles, and authentic Japanese castle fortifications for massive siege engagements.
Installation Dependencies Guide
Before launching any total conversion mod, you must install the standard community modding framework. Most major conversions will crash without these four utility mods placed at the very top of your load order:
| Mod Name | Core Purpose | Download Sources |
|---|---|---|
| Harmony | Enables code patching and mod compatibility. | Steam Workshop / Nexus Mods |
| ButterLib | Extends standard game API functions. | Steam Workshop / Nexus Mods |
| UIExtenderEx | Enables custom UI panels and screens. | Steam Workshop / Nexus Mods |
| Mod Configuration Menu | Adds in-game menu interfaces to configure mods. | Steam Workshop / Nexus Mods |
"Always check the specific version number of the game that a total conversion mod supports. Running a v1.2.0 mod on a v1.2.9 game will cause immediate crashes on launch."
