💠World Structures
Hyperstructures
Hyperstructures are colossal edifices constructed atop ancient foundations hidden across Eternum, representing monumental achievements and symbols of dominance in the game world. Lords must uncover and claim Hyperstructure Foundations through exploration and combat, then invest substantial quantities of resources, labor, and ancient fragments to reconstruct these majestic towers. Successfully completing and controlling Hyperstructures is the primary path to victory in Eternum, making them ultimate strategic targets for ambitious Lords and powerful tribes alike.

Hyperstructure Foundations
These ancient, indestructible platforms are primarily scattered within the ring of Banks that surround the centre of the map. There is a chance of discovering a Hyperstructure Foundation each time an army explores an unrevealed hex, calculated using the following formula:
Discovery Chance = (0.975^x × y) - (z × 0.001)
Where:
- x = the number of hexes from the centre of the map
- y = the base chance of finding a Hyperstructure Foundation on the central hex (4%)
- z = the number of Hyperstructure Foundations already discovered
For example, if you're exploring a hex 100 tiles from the center and 5 foundations have already been discovered:
Discovery Chance = (0.975^100 × 4) - (5 × 0.001)
= (0.079 × 4) - 0.005
= 0.316 - 0.005
= 0.311 or 31.1%
The result of this function means that Hyperstructure Foundations are generally only able to be found within 300 tiles of the centre of the map. As more are found, the chance of finding another diminishes and makes it even less likely to find one further from the centre. Lords are therefore incentivised to explore early in the season to discover these key components for victory.
Hyperstructure Foundations and Hyperstructures both have four defense slots to deter attacks from rival Lords. However, like other world structures they are not able to maintain any field armies.
Fragment Mines
Fragment Mines are rare, ancient nodes scattered throughout the unexplored hexes of Eternum. They produce valuable ancient fragments, a vital resource needed for constructing Hyperstructures. Once discovered by an exploring field army, a Fragment Mine must first be claimed by defeating its resident bandit forces. Only then can Lords begin extracting the mysterious shards hidden within. Each mine contains a finite number of ancient fragments and will permanently cease production when depleted.

The chance of discovering a Fragment Mine when exploring an unrevealed hex is static at 1 in 150, or 0.67%. Mines can contain between 300,000 and 3 million ancient fragments in incremental amounts (i.e. 300k, 600k, 900k…). It will take some time for the full amount of ancient fragments to be produced by the structure, and the more that the mine contains, the longer it will take. Lords will need to ensure that their mines are adequately defended from rivals, however they only have one defense slot to support a guard army.
