Ground

A shadowed eerie biome where the land is filled with deep ravines that produce endless echoes of sounds made hours or years ago. The hollow is an acoustic archive. Ancient battles can still be heard. Some echoes have become self-referential loops.

Settlements

Name	Type	Population	Controlling faction
Echoing Settlement	Faction Outpost	1500	F06 Cogmist Engineers
Echo Hollow	secondary	N/A	F06 Cogmist Engineers
Great Ravine	primary	N/A	F06 Cogmist Engineers

Factions present

Faction	Where recorded
F06 Cogmist Engineers	Home faction of this biome. Controlling faction on every recorded settlement row. All seven NPC rows.

No other faction is recorded on an Echoing Hollow NPC row or settlement row.

The faction named as starting control in the header holds the biome at the start. Control can change during play, and quests follow whoever controls the biome at the time. The faction table also gives F12 Soulglass Circle a foothold here, so the biome is contested.

Signature, primary, secondary, and minerals

These rows are recorded on the B049 resource table and were not in the gatherable list above.

Harvest

The harvestable index records counts for biome 049 only: flora 4, ore 3, trees 3, total 10. That index does not name the rows, so those counts are not assigned to names here.

Named flora recorded for Echoing Hollow:

ID	Name	Harvestable
FLORA-VOID-049	Voidbloom	Yes
FLORA-AETH-049	Aethermoss	Yes
FLORA-HARM-049	Harmonic Crystal Plant	No
FLORA-ARCA-049	Arcane Moss	No
FLORA-PRIS-049	Prism Fern	No
FLORA-COGR-049	Cogrim Orchid	No
FLORA-VOID-049	Void Tendril	No
FLORA-SURG-049	Surge Bloom	No

Two named flora rows are marked harvestable. That does not match the harvestable index count of 4. Duplicate flora ids are left as separate recorded rows. Both figures are left as recorded. The ecological-role cell says PROTECTED SPECIES on Harmonic Crystal Plant, Arcane Moss, Prism Fern, Cogrim Orchid, Void Tendril, and Surge Bloom.

Not recorded: a named tree list, and a named ore list that matches the index counts of 3 and 3.

Difficulty	T3_Heroic
Recommended party	4
Damage type	Frost
Arena	{'location': 'Great Ravine', 'description': "The boss encounter takes place in the heart of Echoing Hollow's most extreme terrain feature. The arena is shaped by arcane anomaly conditions — no neutral ground exists. In 0.68g, player jump arcs extend 47% further than Earth-equivalent, and boss knockback sends players 35% further than expected.", 'arena_size_m': 124, 'special_terrain': 'Echo-amplifying hollow', 'hazard_active': 'Echo Chamber Resonance Rupture'}
Ground blurb	The Reality Prowler the Ancient is the apex expression of Echoing Hollow's ecosystem — a creature that has been shaped by arcane anomaly conditions across centuries of adaptation in 0.68g. It is not simply dangerous. It is what Echoing Hollow would be if the biome could choose to fight.

Weather

The atmosphere row records weather patterns Echo Wind and Sound Rain. Those two names are not rows in the weather table. Six weather rows are recorded for this biome.

ID	Name	Code	Recorded effect
WX-049-STORM	Storm	STORM	Severe visibility reduction. Player movement restricted. Pack predators shelter. Ambush predators peak activity.
WX-049-ASH	Ashfall	ASH	Reduces visibility. Ash-adapted creatures +15% aggro. Node guardian activity increases. Acoustic Crystal harvest modified.
WX-049-SNOW	Cold Event	SNOW	Winter only. Fauna density minimum. Node guardians reduced patrol. Resource yield -20% all types.
WX-049-ANY	Any Weather	ANY	Weather-independent spawn — present in all conditions.
WX-049-RAIN	Rain/Mist	RAIN	Rare moisture event. Suppresses primary hazard temporarily. Most comfortable traversal conditions.
WX-049-CLEAR	Clear Sky	CLEAR	Maximum K3V amber light. Visibility maximum. Best navigation conditions. Standard resource yields.

Spawn entries recorded on those rows: Storm 14, Ashfall 9, Cold Event 12, Any Weather 13, Rain/Mist 6, Clear Sky 16. Night-multiplier entries above 2.0 recorded on those rows: Storm 4, Ashfall 1, Cold Event 3, Any Weather 4, Rain/Mist 1, Clear Sky 2.

Mobs

Five named mobs are recorded. One further row records 65 additional spawn-table entries that are not named. Those 65 are not listed as species here. That summary row records 20 corrupted variants and 0 event overrides. Its weather distribution cells are all zero. Acousticwatcher has archetype Node Guardian but the node-guardian cell reads False. Both are left as recorded.

The node-network file records a guardian name string on each of these sixteen nodes. Those strings are not rows in the named mob list above. The biome file, used in this table, records no guardian on the eight positive nodes and a guardian present on the eight negative nodes. Both records are left as recorded.

World events

Three world events are recorded. Where the duration cell and the notes cell disagree, both figures are left as recorded. The biome-pack names and the world-event master names disagree. Both name sets are left as recorded.

Recipes

Sixteen recipes are recorded, one for each item above. Output quantity is 1. The third material cell is blank on every row, so no third material is listed. Recipe unlock cells use T1 Known, T2 Trusted, T3 Honoured, and T4 Honoured. The faction reputation row names those bands T1 Neutral, T2 Friendly, T3 Honoured, and T4 Revered. Both wordings are left as recorded.

Image prompt

Text only. No file is uploaded. The prompt below is the recorded overview prompt for B049, followed by the ground description and settlement names already on this page.

Recorded overview prompt: ABERNON game concept art, Biome 049 Echoing Hollow, K3V amber light, arcane_anomaly environment, 0.68g low gravity, Cogmist Engineers faction territory, AAA game quality, cinematic painterly, panoramic establishing shot, biome landscape at K3V amber light, faction settlement visible, atmosphere establishes biome identity.

Detailed prompt for an image creator: Painterly cinematic establishing shot of Echoing Hollow, biome 049, arcane anomaly, under K3V amber light at 0.68g. A shadowed eerie biome where the land is filled with deep ravines that produce endless echoes of sounds made hours or years ago. The hollow is an acoustic archive. Ancient battles can still be heard. Some echoes have become self-referential loops. Terrain recorded as echo-amplifying hollow. Reality bends. Geometry is unreliable. Arcane energy surges without warning. Echo Chamber Resonance Rupture is the recorded primary hazard. Acoustic Crystal is the signature resource. Recorded colour palette: violet, prismatic, silv. The Cogmist Engineers settlement Echoing Settlement is visible, with Echo Hollow and Great Ravine in the same territory. AAA game concept art, faction territory readable in the architecture, no text in the image.

The image-prompt table also records twenty ungenerated prompts, IMG00961 through IMG00980. Each uses this recorded stem, with the type name in place of the scene type: AAA game concept art, Echoing Hollow, arcane anomaly biome, [type], reality distortion, arcane energy surges, amber and void contrast, Echo Chamber Resonance Rupture environmental hazard visible, Unreal Engine 5 quality, painterly, cinematic lighting, amber K3V star palette, alien yet familiar world aesthetic.
