The Last Fragment

The Last Fragment

Build a home in the void, hold reality together and venture through Rifts to reclaim a shattered world.

The Last Fragment is a custom survival progression modpack for Minecraft 1.21.1 / NeoForge, built around the Riftbound mod and its Codex. Grow a floating island, strengthen the Anchor, build a production system and conquer two playable Rift worlds.

Progression and exploration

• Start with Tier 0 resource processing, hammering, sieving and renewable materials.
• Upgrade the Anchor to unlock new islands while managing Reality Stability, Load and Capacity. Expand your home island through building.
• Explore The Forgotten Grove and The Ashen Vale, complete trials and defeat their rulers.
• Unlock Grove and Ashen technology, Warden equipment, relics and artifacts.
• Meet The Witness, whose relationship with you develops through your actions.
• Build Matter processing, transmutation, power generation, storage, wireless systems, logistics and Rift Snare automation.
• Follow the Codex with Tab; use JEI for recipes, processing and Matter information.

The latest version includes placeable Dust, conduit filters, local Matter balances, clearer machine information, Anchor warnings, improved storm formation and Voidwalker movement improvements.

Included mods and shaders

The pack includes Riftbound 0.14.1, GeckoLib 4.9.3, JEI 19.57.0.450, Iris 1.8.12, Sodium 0.6.13 and the Riftmode 1.0.4 shaderpack. All downloads reference their CurseForge projects.

Riftmode starts on Balanced. Choose Potato or Low if needed, or disable shaders in Iris while keeping the same gameplay. The live Iris integration is already built into Riftbound.

Getting started

• Use Minecraft 1.21.1, NeoForge 21.1.252 and Java 21. Allocate 6 GB RAM if available.
• Create a new Survival world using the Riftbound Void world type.
• Open the Codex with Tab and start with the Tier 0 objectives.
• Keep co-op clients and servers on matching Riftbound versions.
