At a Glance
- Type
- One of the Nine Dungeons: the colossal subterranean fortresses that erupted across Talan in 2524 MR and disgorged the first great corruption armies of the modern age. See The Binding for the full Nine-Generals framework.
- Position
- Beneath the deep forest of Itzasoa in Myrkono (Darkness / Araphel), the Surki's woven wood. Dangerously close to two Wardstones: the Forest Wardstone of Ehunbaso and the mountain Temple Wardstone, both within Itzasoa.
- Master
- The Vermin Queen: one of the Nine Generals of Corruption. Mistress of swarms.
- Doctrine
- Grants the Swarm domain to clerics who turn to corruption through her vessel. See PF2e Registrar → Cleric Domain Granters.
- Status
- Main entrance sealed after the first-wave campaigns of 2524–2528 MR. Containment-only since; smaller leakage continues through tunnel networks the seals do not reach.

The Hollow's Geography
A vast cavern system deep beneath the earth, transformed into a hive of spiders, centipedes, beetles, and crawling horrors. Named for the endless webs threading its chambers, strands infused with corruption, glistening with sickly light, strong enough to bind armoured warriors. Four chamber-types recur throughout the system and define the operational geography:
The Web-Tunnels
Narrow passageways coated in sticky threads. Trap and alarm system in one · intrusions alert the Queen's spawn instantly. The Tunnels are the dungeon's connective tissue and its outer warning layer. No deep penetration of the Hollow begins anywhere else.
The Brood Pits
Chambers full of eggs, larvae, and swollen brood-mothers. The Pits are where the swarms come from. Tarry too long and the hatchlings overwhelm; clear a Pit and another swells to take its place within seasons. The Pits are the reason containment, not eradication, is the doctrine.
The Silken Vaults
Cocooned bodies · mortal victims, beasts, and adventurers. Some still live, transforming slowly into monstrosities through corruption seeping from the silk. A Vault's worth of cocoons is the Hollow's grimmest cargo: every one is a story, and most are unfinished.
The Throne of the Vermin Queen
Chamber vast enough to contain her massive form. Draped in layers of living web. She is attended by her chosen spawn · grotesque spider-hybrids once human, now twisted. No expedition has reached the Throne and returned. The few that have reached it had no survivors to bring word.
The Three Threats
Veterans of the Itzasoa campaigns describe the Hollow as three problems wearing one shape. Each can kill on its own; in combination they erode the rolls of even high-rank Guild parties. They are taught at Myrria's Godshall as the canonical example of why Nine-Dungeons containment requires specialised doctrine, not just martial skill.
Endless Swarms
The Hollow's strength lies in the unending tide as much as the Queen herself. A party can cut a thousand and meet two thousand before the silk dries on the first cut. Numbers attrition, the Guild calls it, and the Hollow has Brood Pits enough to attrition any expedition the kingdoms can field, given time.
Corrupted Silk
The webs are not mere thread. They carry the Blightfather's power · sticky enough to bind armoured warriors, slow-poisoning to weapons and armour that touch them. Steel pitted by silk fails sooner than steel struck a hundred times. Wounds taken while bound heal slowly or not at all. A Hollow expedition prepares as much for material decay as for combat.
Hive-Mind Influence
Long exposure fills intruders with whispers: fragmented compulsions to stop fighting, to lie down, to join. The swarm itself wears down willpower; the corruption-soaked air is part of the attack. Parties that linger past a certain duration begin to lose members not to combat but to drift: adventurers who walked into a cocoon of their own choosing and could not be retrieved.
The Vermin Queen
One of the Nine Generals of Corruption: the foremost servants of the Corrupted God, wrought from his power while he remains bound. Originally a mortal cultist, cleric, beast, or nameless horror from a deep place (canonical record disagrees), the Queen was chosen and remade into a vessel of corruption's will. Unlike her imprisoned master, she can be fought and slain: though no expedition has yet succeeded.
Her nature is mistress of swarms. She breeds endless spiders, locusts, centipedes, beetles, crawling things, when her children stir, they pour out in tides that choke entire valleys. She rules from the Throne chamber, attended by her chosen spawn. The Hollow itself is partly her body, the silk is hers, the broods are hers, the hive-mind influence is hers extended.
She grants the Swarm domain to mortals who turn to corruption through her, clerics whose faith chooses the hive over the self. There are not many. There are some. They tend to vanish into the Itzasoa deep within a year of conversion. Where they go is, technically, an open question.
Destroying her would scatter her hive and collapse much of the Hollow. The mathematics of the War of Seals say this loudly. The mathematics of the Throne's survival rate say something else.
The Surki Counter
Insectoid, but not Corrupted
The Surki: insectoid sapients of the deep places, hold a doctrinal position on the Vermin Queen that mortals elsewhere often miss. The Surki are insectoid by anatomy: compound eyes, chitinous segmentation, hive-adjacent biology. The Vermin Queen's swarm-corruption is precisely the fate they organise to resist.
The opposition is doctrinal, cultural, and operational. The Surki, in whose own Itzasoa wood the Hollow breeds, are among the most informed and most committed allies any Guild expedition into the Hollow can hope for. They know the swarm-vocabulary; they read the silk-patterns; they understand the hive-mind influence as kin gone wrong, which is the only frame in which it can be effectively resisted rather than merely endured. A Hollow expedition with a Surki scout-or-advisor is materially more likely to come back than one without.
The Surki have not made a public alliance with the Adventurers' Guild, they don't make public alliances generally, but the working relationship at the Hollow's margin in Itzasoa is real and centuries deep. The Hollow's eruption in 2524 MR has only sharpened it.
⌬ Open in the Chronicle Record
The Hollow is a fully canonised threat-site; specific operational details remain open for future story-driven work.
- The Vermin Queen's origin: canonical record disagrees on whether she was originally a mortal cultist, a cleric, a beast, or a nameless horror; the actual answer is open
- Specific Guild expeditions: high-rank operations against the Hollow over the past eight years presumably exist; named parties, named survivors, named losses are unwritten
- Surki organisational structure: the doctrinal-cultural-operational opposition is canon; the specific Surki institutions, leadership, or coordination methods are unwritten
- Specific Swarm-domain clerics on record: there are *some* but they tend to vanish into the Itzasoa deep within a year; the Guild's tracking effort and named individuals are open
- The other seven Generals' dungeons: the Hollow is the only Nine-Dungeons site written up as its own page so far. The Maw Serpent is now sited (sealed beneath the north pack-ice of Baerfrost, Vindul). The other six (Rot-Tyrant, Blight-Seer, Flesh-Sculptor, Whisperer in Dreams, False Saint, Root-Twister) exist in canon and will earn their own pages as the detail develops
