Installation

Get Frontier running in a few minutes. Drop in the JAR, create an arena, done.

Prerequisites

Make sure these are already on your server:

• Minecraft 1.21.1 with Fabric
• Fabric Loader 0.16.0 or newer
• Fabric API
• Fabric Language Kotlin
• Cobblemon 1.6.0 or newer
• Ceremony 4.3.9 or newer

Setup

1. Install the Mod

Place the Frontier .jar file in your server’s mods/ directory alongside Cobblemon and Ceremony.

2. Generate Config

Start the server. Frontier creates its config directory at config/frontier/ with default configuration files. All seven default ladders are ready to go.

3. Create an Arena

Arenas are where ranked matches take place. You need at least one. The built-in wizard walks you through it:

/ranked admin arena create main

Stand at the position where Player 1 should spawn:

/ranked admin arena setpos1

Move to Player 2’s spawn:

/ranked admin arena setpos2

Optionally, move to where spectators should watch from:

/ranked admin arena setspectator

Save the arena:

/ranked admin arena done

Multiple Arenas

Create as many arenas as you want. More arenas means more simultaneous matches. Just run the wizard again with a different ID — /ranked admin arena create arena2.

4. Test It

That’s it. Players can now use /ranked to open the hub GUI or /ranked queue singles to join a queue.

Storage

Frontier uses Ceremony’s storage system for all persistent data. The storage backend is configured in config/ceremony/config.conf, not in Frontier’s config.

Backend	Use Case
JSON	Development, small servers
SQLITE	Single servers, moderate populations
MONGO_DB	Production, multi-server networks
MARIA_DB	MySQL-compatible environments

Persistent Collections

Frontier stores data across five collections:

Collection	Content
frontier_ratings	Player ratings per ladder
frontier_matches	Completed match records
frontier_milestones	Milestone claim tracking
frontier_season_archives	End-of-season snapshots
frontier_pending_rewards	Queued rewards for offline players

Shared Storage

If you’re running multiple servers, point them at the same MongoDB or MariaDB instance through Ceremony. Ratings and match history carry across servers automatically.

First-Run Checklist

Run through these after your first boot:

• Server starts without errors
• config/frontier/ directory is populated with config files
• At least one arena is created (/ranked admin arena list to verify)
• Test a match: two players queue for the same ladder
• Verify ratings update after the match (/ranked stats)

Arena Required

Matches can’t start without at least one arena. If players queue but nothing happens, check that you’ve completed the arena wizard with /ranked admin arena done.
