This is the public-facing version of the stack: enough detail for curious players and builders, without requiring server console access.

1 Core server

LayerWhat it doesWhy AOW uses it
Paper 1.21.8Runs the Java server and plugin API.Modern performance, Bukkit/Paper events, Adventure text, and a strong plugin ecosystem.
Java runtimeRuns the Paper process.Server docs reference Temurin/OpenJDK and a tuned JVM heap.
systemdKeeps the Minecraft service managed on the VPS.Starts on boot and gives staff a predictable service workflow.
BackupsPreserve server and world data.Protects the SMP from accidental loss.

2 Crossplay chain

Java player   -> TCP 25565 -> Paper
Bedrock user  -> UDP 19132 -> Geyser -> ViaVersion -> Paper
Auth layer    -> Floodgate -> Bedrock identity without Java purchase
Geyser

Accepts Bedrock traffic and translates it into Java protocol behavior.

Floodgate

Lets Bedrock players authenticate with their Microsoft/Xbox account while the server stays secure.

ViaVersion

Keeps protocol versions aligned between clients, Geyser, and Paper.

5 Custom plugin rules

The AoW custom plugins follow a tight design rule: add useful server-side flavor without forcing client-side mods. The flagship custom system is Mythic Champions — any mob can spawn as a titled, named Champion across 8 tiers with archetype titles, affixes, signature attacks, a living world, and tier-scaled loot.

  • Paper API only.
  • Adventure components for modern text.
  • PersistentDataContainer for item/player metadata where needed.
  • Vanilla items and blocks only.
  • ADD-only behavior: enrich vanilla without stripping it away.
  • Config-toggleable features so staff can tune each system.
  • Bedrock-safe behavior that works after Geyser translation.
