🗺️ A New Region for Baldur's Gate 3
Baldur's Gate 3 has just received one of its most ambitious fan projects yet.
Created by modder SquallyDaBeanz, the Act Two Expansion - Custom Campaign adds a completely new region called the Chionthar Wilds between the game's second and third acts. The beta launched on September 17 after almost two years of development.
This isn't simply a collection of new items or cosmetic changes.
The project adds quests, dungeons, NPCs, cutscenes, lore, puzzles, custom creatures and new combat encounters, effectively creating a new adventure inside the existing Baldur's Gate 3 framework.
🌲 Welcome to the Chionthar Wilds
The new region takes place after the Shadow-Cursed Lands and before the player reaches Baldur's Gate.
The expansion is designed around level 8-10 parties, giving experienced characters a new area to explore without completely disrupting the game's existing progression.
The region focuses heavily on exploration and combat while expanding the world with:
New quests
New dungeons
New NPCs
New cutscenes
New lore
New puzzles
New secrets
Custom creatures
70+ new items
30+ combat encounters
That scope is what makes the project stand out from a typical community mod.
⚔️ It Feels Like a New Act
The creator's goal isn't simply to add another dungeon to the game.
The expansion is structured around creating a new region with its own exploration and combat loop, similar in spirit to the large wilderness areas found earlier in Baldur's Gate 3.
Players can explore the area, discover secrets, fight new enemies and complete additional quests before continuing toward Act 3.
The main version integrates the content directly into the existing campaign, while a separate QuickStart version lets players jump into the expansion immediately with a new save.
🛠️ How Did One Creator Build This?
This is where Larian's modding support becomes the real story.
Larian officially introduced the Baldur's Gate 3 Toolkit alongside Patch 7, giving community creators access to parts of the development tools used to build the game. The toolkit includes editors for creating mods, level editing and testing tools, supported asset editors and systems for packaging and publishing mods.
Larian also designed its official mod pipeline around mod.io, allowing players to discover and manage supported mods directly through the game.
That infrastructure effectively gave experienced creators access to many of the building blocks needed to produce content that feels much closer to a developer-made expansion.
🧰 More Than a Simple Mod
The scale of the Act Two Expansion demonstrates what happens when those tools are placed in the hands of a dedicated creator.
Instead of changing one mechanic, the project combines:
World Design + Quests + Characters + Combat + Items + Dialogue + Exploration
The result is closer to a community-built mini-campaign than a conventional gameplay tweak.
The project page also credits the wider BG3 modding community and specifically thanks the creators of tools and projects that helped make this kind of work possible.
💾 Can You Use an Existing Save?
Yes, with an important condition.
The main version is designed to work with existing saves, provided the mod is installed before leaving Act 2. Players can then access the new region as part of the transition toward Act 3.
There is also the QuickStart version for players who want to experience the expansion without playing through the earlier acts first.
Because this is a beta release, the creator recommends saving regularly and warns that some bugs can occur.
🧙 Why This Matters for Baldur's Gate 3
The interesting part isn't simply that Baldur's Gate 3 has received another mod.
It's what the project says about the game's longevity.
Larian built Baldur's Gate 3 around a huge number of interconnected systems. By exposing parts of that development infrastructure to the community, the studio has allowed creators to experiment with the same kinds of building blocks that make the original game so flexible.
The Act Two Expansion is a particularly visible example of that philosophy in action.
🌟 The Bigger Modding Picture
Larian has continued encouraging the community to create new content. In one official community update, the studio highlighted a month-long Modathon in which 85 mod authors created more than 160 mods, demonstrating the scale of the game's modding community.
The Act Two Expansion takes that idea considerably further.
It shows that community creators aren't limited to adding hats, weapons or small gameplay tweaks. With enough time and technical knowledge, they can build substantial new spaces and adventures inside the Baldur's Gate 3 framework.
🎯 Final Take
The Act Two Expansion - Custom Campaign is a remarkable example of what Baldur's Gate 3's modding ecosystem can produce.
After nearly two years of development, SquallyDaBeanz has created the Chionthar Wilds, a new region filled with quests, dungeons, characters, encounters, items and secrets.
But the bigger story is Larian's toolkit.
By opening up parts of its development pipeline, Larian has given experienced fans the ability to go far beyond traditional modding. This expansion is a glimpse at what Baldur's Gate 3 can become when the community gets the tools to build its own adventures.
