Verity mod install 1.21.1 on Lunar Client — use community fork instead

The Verity mod install for 1.21.1 on Lunar Client is not available. The 1.21.1 community fork runs on NeoForge only. Below is the full explanation and your options to get the Verity mod for Minecraft 1.21.1 running.

Why the Verity mod 1.21.1 install is not on Lunar Client

The Verity mod 1.21.1 install is not available on Lunar Client because the official Verity mod distribution deal signed in early 2026 covers Minecraft Java 1.20.1, 1.20.4, and 1.21 only. Lunar Client does not ship a 1.21.1 modpack, and ThatMobb (the mod author) has not announced a 1.21.1 Lunar Client release. Any Lunar Client page that claims to host a Verity mod 1.21.1 build is either a redirect, an outdated copy, or malware.

The Verity mod install for 1.21.1 is a community-maintained fork called Verity-CE, developed by Esylmu on GitHub. Esylmu forked the 2.1.0 Verity mod source when ThatMobb declined to backport to 1.21.1, and the community fork is the canonical install path for Verity 1.21.1.

Your options for the Verity mod 1.21.1 install

There are exactly three options for the Verity mod 1.21.1 install. Each takes a different amount of time and has a different community size. Pick the one that fits your situation.

Option 1: install the Verity mod 1.21.1 community fork on NeoForge — see the [NeoForge install guide](/en/install/1.21.1/forge) for step-by-step. Option 2: downgrade to Minecraft 1.21 and install the Verity mod official build on Lunar Client — the install is identical to other Lunar Client modpack installs. Option 3: wait for an official Verity mod 1.21.1 release — none is announced and there is no timeline.

What you get with the Verity mod 1.21.1 community fork install

The Verity mod 1.21.1 community fork (Verity-CE) has full feature parity with the official 1.21 / 1.20.4 / 1.20.1 builds. All 8 systems (Dynamic AI, Progressive Horror, Voice Synthesis, Facial Animation, Story Engine, Animations, Spatial Audio, Multiplayer-aware) work the same way. The 1.21.1 community fork also adds one feature the official builds do not have: configurable OpenAI-compatible API endpoint for dialogue generation. You can self-host the dialogue model or point Verity's AI at any OpenAI-compatible API.

What the Verity mod 1.21.1 community fork install does NOT have, compared to the official Lunar Client builds: no auto-updates (you have to download new JARs manually from GitHub Releases), no Lunar Client cosmetic integration (capes, wings, hats do not show for Verity-related events), and no official modpack store page. The community fork is community-supported, not officially endorsed by ThatMobb or Lunar Client.

Will the Verity mod 1.21.1 install come to Lunar Client

Probably not. ThatMobb has stated in the Verity mod Discord that the exclusive Lunar Client distribution deal is permanent for the foreseeable future. The deal does not include 1.21.1 specifically. The community fork exists because Lunar Client's roadmap is locked to 1.20.1 / 1.20.4 / 1.21. The deal does not have an end date. Any 1.21.1 Lunar Client modpack would require breaking the deal or expanding it, neither of which is on the public roadmap.

If you specifically need the Verity mod 1.21.1 install on Lunar Client, your only option is to ask Lunar Client to add 1.21.1 to their modpack supported versions. The Lunar Client Discord has a #modpack-requests channel where you can submit a request. The Verity mod team will not be able to push Lunar Client to add 1.21.1 — that decision is on the Lunar Client side.

Verity mod install 1.21.1 on Lunar Client — FAQ

Can I install the Verity mod 1.21.1 on Lunar Client using the modpack store?

No. The Lunar Client modpack store does not list a Verity mod 1.21.1 build. The official modpack covers 1.20.1, 1.20.4, and 1.21 only. If you see a Verity mod 1.21.1 listing in the Lunar Client modpack store, it is a fake / outdated build / malware. Report it to Lunar Client support and do not install.

Is the Verity mod 1.21.1 community fork install safe?

Yes. The Verity-CE JAR is open-source on github.com/Esylmu/Verity-CE and has been audited by the community. The release JARs are signed with Esylmu's GPG key. Install only from the official GitHub Releases page — do not install from any third-party download site. See the [Verity mod FAQ](/en/wiki/faq) for the full safety check procedure.

What if I really want the Verity mod 1.21.1 on Lunar Client?

The closest workaround is to install the Verity mod 1.21 community fork on NeoForge, and add a Lunar Client profile in your launcher that points at the same `mods` folder. This is an unsupported setup and may cause launcher conflicts, but some users report it working for casual play. The official recommendation is to pick one launcher (Lunar Client or NeoForge) and use the matching Verity mod build.

What does the Verity mod 1.21.1 community fork install do that the official builds do not?

The community fork adds a configurable OpenAI-compatible API endpoint for dialogue generation. The official Verity mod install uses ThatMobb's backend (api.verity-mod.com) for AI dialogue. The community fork lets you self-host the dialogue model — point Verity at any OpenAI-compatible API (local Ollama, OpenRouter, Together.ai, LM Studio, etc.) and the AI dialogue will use your model instead. The fork is functionally identical for everything else: the 8 systems, the 1.21.1-specific bugs from the community fork's GeckoLib 4.9.1 dependency, and the multiplayer behavior. There is no official endorsement from ThatMobb or Lunar Client for this fork.

Can I get the Verity mod install 1.21.1 on Lunar Client if I downgrade Lunar Client to an older version?

No. Lunar Client has never shipped a 1.21.1 modpack. Older Lunar Client versions do not have 1.21.1 support either. Lunar Client's modpack versioning is tied to the Minecraft version — the 1.21 modpack includes Verity mod build x.y.z, the 1.21.1 modpack would include Verity mod build x.y.z+1 (which does not exist). Downgrading Lunar Client does not give you 1.21.1 support. The only Lunar Client path is the 1.20.1 / 1.20.4 / 1.21 official builds.

How long does the Verity mod install 1.21.1 take on NeoForge?

The Verity mod install 1.21.1 on NeoForge takes about 8 minutes from a clean install: 2 minutes to download the NeoForge 1.21.1 installer, 1 minute to install NeoForge, 30 seconds to download the Verity-CE JAR from GitHub Releases, 30 seconds to download GeckoLib 4.9.1 from CurseForge, 3 minutes of in-game world join + first Verity encounter. The community fork does not auto-update — you will need to manually download new Verity-CE JARs from GitHub Releases when new versions are tagged. The typical release cadence is one Verity-CE JAR per month, sometimes more if the community fork is keeping pace with the official Verity mod's 2.1.x train.
