Relic Worm

Relic Worms are small, swarm-forming monsters of the Fourth Floor whose defining threat is not raw physical size but their ability to invade the equipment on which a Climber depends. They occupy an uneasy boundary between creature and sabotage mechanism: a hunt for them can become a fight against the sudden failure of the hunter’s own Relics. That disproportion between their modest value and the catastrophic consequences of encountering them makes them one of the clearest examples of how survival in The Tower is governed by equipment, information, and risk as much as by combat strength.

Nature and Habitat

Relic Worms are technically Fourth-Floor monsters, but they are associated specifically with the murky swamps of that Floor. Each worm is palm-length and thin as a few hairs, a form that allows it to burrow through flesh and Relics with equal voracity. Their physical minuteness is therefore misleading: what appears individually insignificant becomes overwhelming when the creatures attack collectively.

They travel in swarms numbering in the tens of thousands. Rather than meeting Climbers in open combat, they swim through concealing swamp water and strike at the legs of people wading through it. The environment is part of their weaponry. The water hides the approach of the swarm, restricts movement, and makes it difficult to identify the danger before the worms have already reached their targets.

Effect on Climbers and Relics

The Relic Worm’s most feared behavior is infestation. The creatures can enter a Climber’s Relics, disabling them without warning and turning an ordinary encounter into a life-or-death emergency. This makes their danger relational: the same equipment that normally provides protection or power becomes the site through which the threat acts.

The consequences extend beyond physical injury. A Relic is often extremely valuable, and a worm swarm can eat through boots or weapons, destroying more wealth than the worms themselves are worth. Worse, the sudden loss of an item’s power can expose a Climber to immediate danger. A person who has survived by relying on a Relic may be left vulnerable at precisely the moment the equipment fails, so infestation can produce a cascading loss of defense, mobility, and combat ability.

This risk explains the creature’s reputation. Low-level Climbers may simply die while attempting to hunt Relic Worms. High-level Climbers possess better equipment but have more to lose, and their valuable Relics make them reluctant to expose themselves to a creature capable of disabling or consuming that equipment. The worms thus invert the usual logic of progression: greater wealth and stronger gear do not automatically make the hunt attractive, because they increase the cost of failure.

The Cost of Hunting Them

The only Climbers who might safely hunt Relic Worms are those powerful enough to subdue them entirely without using Relics. That solution removes the creatures’ principal advantage, but it also creates an economic problem. Climbers capable of such a hunt would ordinarily be strong enough to possess a Demesne on the upper Floors, making a dangerous expedition for a comparatively modest reward an unattractive use of their time.

Relic Worms consequently occupy a neglected position in the Tower’s economy. They are difficult enough to kill that weak Climbers cannot safely pursue them, but insufficiently valuable to tempt the strongest Climbers away from more profitable opportunities. Their danger is reinforced by this lack of specialization: the creature remains available as a threat even though few people have a practical reason to seek it.

Connection to the Phantom Hand

For Will, the Relic Worm becomes important because of the Phantom Hand’s possible progression. One prospective upgrade, Relic Focus, requires the sacrifice of a Relic Worm. In exchange, the Phantom Hand’s Scaling could apply to any Relic effects imprinted on it, potentially allowing Will’s Acuity to increase the effectiveness of those Relic effects. The requirement turns an obscure and hazardous swamp creature into a central component of Will’s long-term build.

The upgrade’s promise is described as obscene power, but its price is not abstract. Will must personally obtain the required sacrifice from the Fourth-Floor swamps, where a swarm could disable his equipment, consume his boots or weapon, or remove the very powers needed to survive the encounter. The system’s reward structure therefore converts a creature that most Climbers avoid into a deliberate objective for Will, forcing him to exchange immediate safety for a potentially transformative increase in capability.

Narrative Significance

Relic Worms embody the Tower’s broader principle that danger often emerges through infrastructure rather than spectacle. Their bodies are tiny, their value is modest, and their attack may remain unseen until equipment fails; nevertheless, they can kill low-level Climbers and threaten even veterans. The creature’s horror lies in anticipation and vulnerability before it lies in appearance: the fear that a familiar Relic may stop working while its owner is still trapped in the swamp.

They also expose the material dependence beneath the Tower’s progression system. A Climber’s strength is not contained solely in the body or in abstract statistics; it is distributed across gear, abilities, terrain, and the rules governing sacrifices. Relic Worms attack that network by turning equipment into a point of entry. Their role in Will’s planned Phantom Hand upgrade sharpens the irony: the creature most likely to destroy a Climber’s build is also the sacrifice that may allow Will to make his build vastly more powerful.
