What is inside the stone

FTB StoneBlock 4 starts you on an island of stone with no sky and builds out through FTB Quests, six Foundation Chapters and a World Engine with over 15 multiblock upgrades. It runs on NeoForge for Minecraft 1.21.1 and mixes Create, Mekanism, Ars Nouveau, Draconic Evolution and the Twilight Forest. It suits solo players and friend groups who want a guided, quest-driven tech and magic climb.

  • Garden of Stone and five starts

    Pick one of five starting islands, then work through six Foundation Chapters in FTB Quests. Each chapter branches, and finishing the paths awakens more Echoes.

  • Vaults and Echoes

    Handcrafted Vaults test you with logic puzzles, combat and endurance and pay out rare loot. Echoes are holographic guides that hand out quests and trade.

  • World Engine and the Unearther

    The World Engine unlocks crafting tiers through more than 15 multiblock upgrades. The Unearther puts a villager to work sifting debris, and he gets better the more you feed and equip him.

  3. 03

    Start and play

    Start the server and share the address. We suggest 8 GB to start with for this pack, and you can change plans later.

Managed Modpack Setup is free: if the install needs a hand, staff finish it for you.

A Create, Mekanism and Replication base keeps a server's tick loop busy.

Every Pyro Minecraft server runs on an AMD Ryzen 9 9950X with NVMe storage, behind DDoS protection, with 128 backup slots.

Machine networks need fast cores

StoneBlock 4 pairs Create contraptions, Mekanism processing and Replication with KubeJS scripts that drive the World Engine and Vaults. That is a lot of block entities and script work on the main thread, which the AMD Ryzen 9 9950X's single-core speed handles well.

Startup and chunk loading on NVMe

The pack loads hundreds of mods, so boot time and region reads add up. NVMe storage shortens both, and Vault and Twilight Forest exploration reads fresh chunks quickly.

Backups before big upgrades

Draconic Evolution and World Engine progress are expensive to redo. 128 backup slots let you snapshot before each milestone, and DDoS protection keeps a public friend server reachable.

Footnotes

  1. Nodes feature 10 Gbps uplinks to the Internet, delivering "warp-speed" throughput.
  2. Regional ping averages are ~65 ms to our datacenters, ensuring "ultra-low" latency.
  3. The AMD Ryzen 9950X is our standard processor across all regions. In rare cases where the 9950X is unavailable, we deploy only equivalent AM5 processors with boost clocks matching or exceeding the 9950X that we've benchmarked to ensure no noticeable performance difference. Our systems maintain maximum boost speeds continuously, ensuring you always receive 9950X-level performance.
