Imperium is an adventure and progression mod that adds new content inspired by the lore of an ancient empire.
It was originally created for a private server with friends, where the mod was part of the world’s story and its characters. It began as a personal project for that server, but is now publicly available so any player can explore it and adapt its content to their own world.
Although part of the lore was born inside that server, the mod also works as a standalone Minecraft expansion, adding ancient structures, powerful relics, ritual systems, unusual combat mechanics, custom advancements, and hidden rewards.
What does it add?
Large structures to discover, including Imperial Outposts, quarries, camps, and several kinds of ruined portals.
The Fallen Sword, an ancient blade that can be restored through an Imperial ritual.
The Sentencia del Monarca, a forbidden weapon built around condemnation, judgement, and irreversible consequences.
The Imperial Totem and the Monarch’s Ring, two relics connected to the Empire’s legacy.
Expanded Blood Curse progression for swords and axes.
ULTRAKILL-inspired Imperial Coins with ricochets, accumulated damage, split timing, projectile parries, and other secret interactions.
Aurum, an ancient imperial material used to construct altars, teleportation anchors, prisms, and configurable shield emitters.
Long-distance travel through the Imperial Anchor Network.
Customizable barriers capable of controlling players, creatures, projectiles, and access permissions.
New building materials, including ash, Blood Grass, and a complete Ashen Wood set.
New rituals, custom advancements, particles, sounds, visual effects, and secrets.
About the lore
The mod is based on a story created for a server with friends, so some names, items, structures, and advancements may feel more narrative than in a traditional mod.
The main idea revolves around the Empire, the legacy of the First Monarch, ancient weapons, broken oaths, forgotten technology, and relics with special power.
You do not need to know the original lore to play it. The mod is designed so it can be enjoyed as an adventure, exploration, combat, and reward-based expansion.
Credits & Inspiration
Imperial Coin combat is inspired by the coin mechanics from ULTRAKILL. Imperium Mod is an independent, unofficial project and is not affiliated with or endorsed by New Blood Interactive or the ULTRAKILL development team. No code or assets from ULTRAKILL are included.
