Warforged Colossus

Source: Eberron: Rising from the Last War p. 314

In the final days of the Last War, House Cannith unleashed its mightiest creations: the warforged colossi. These enormous mechanical warriors thundered across Cyre, crushing everything in their paths and leaving ruin behind them. Meant to end the war decisively, the colossi pulverized hundreds of soldiers beneath their feet and incinerated whole legions with beams of fiery light that shot from their mouths. This rampage was cut short on the Day of Mourning. The arcane cataclysm that engulfed Cyre destroyed most of the warforged colossi, causing them to collapse into lifeless heaps.

Colossal Survivors

Some warforged colossi survived the Day of Mourning more or less intact and are thought to only be in stasis, waiting to be awakened. Cannith artificers are eager to track them down and determine whether they can be awakened or, at the very least, salvaged for docents and other magic items. Here are locations where operational warforged colossi are rumored to dwell:

  • “Arkus” (Colossus WX-11) lies prone at the bottom of the Glowing Chasm in the northern part of the Mournland, with one of its arms torn off.
  • “Artorok” (Colossus WX-73) sits at the bottom of Lake Cyre amid the scaffolding of a sunken House Cannith workshop, flooded but otherwise intact.
  • “Hanamar” (Colossus WX-42) stands at the bottom of Kraken Bay, near the coast of Valenar, buried up to its knees in sand and flooded, but it is otherwise intact.
  • “Karrnslayer” (Colossus WX-31) lost its legs but crawls through the Mournland, using its arms to drag its great bulk across the ground. It is always prone and can’t use its Stomp action, but makes three extra turret attacks when it takes the Multiattack action option.
  • “Landro” (Colossus WX-33) is partially phased into a mountainside on the border of Cyre and Breland, but still explorable and potentially salvageable.
  • “Norr” (Colossus WX-5) is slumped amid the ruins of Metrol, the former capital of Cyre.
  • “Tymber” (Colossus WX-12) squats in the Crawling Swamp, in the northwest corner of the Shadow Marches. How it got there, no one knows.

Hollow Structure

Although it can operate without a crew, a warforged colossus is built to carry wizards, artificers, magewrights, and elite troops. For this reason, these constructs are largely hollow on the inside, with tunnels, ladders, storage areas, and observation decks.

A colossus might be filled with monsters and secrets, in addition to the corpses of those who died inside it. In chapter 4, map 4.8 illustrates an inactive warforged colossus, and the text that accompanies it explains how the colossus might serve as an adventure location.

      \nStructures, as well as nonmagical objects that are neither being worn nor\
