Ground

A broken rift of sunken wilds where roots protrude from every crack and the earth coils with hunger. The hollow was formed when a tectonic plate collapsed inward trapping an ancient forest beneath the surface. The roots still grow upward seeking light.

Settlements

Name	Type	Population	Controlling faction
Root Hollow	primary	N/A	Riftwalker Brotherhood (VANISHED)
Sunken Forest Rift	secondary	N/A	Riftwalker Brotherhood (VANISHED)
Thornhollow Settlement	Faction Outpost	1500	Riftwalker Brotherhood (VANISHED)

Factions present

Faction	Where recorded
F05 Riftwalker Brotherhood	Home faction of this biome. Controlling faction on every recorded settlement row, shown there as vanished.
F08 Frosthold Vigil	All seven NPC rows.

NPCs here from other factions: F08 Frosthold Vigil (7 NPC rows). An NPC can belong to any faction and live or work in a settlement controlled by another faction.

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 stored faction key "Riftwalker Brotherhood (VANISHED)" is kept as written in the tables above. The VANISHED label refers to the original nine members of the Brotherhood, who departed. Outsiders call them the Vanished. Current members of the Brotherhood call them the Ascended. Both are true depending on who is speaking.

Signature, primary, secondary, and minerals

These rows are recorded on the B020 resource table and were not in the gatherable list above.

ID	Name	Type	Rarity

Harvest

The harvestable index records counts for biome 020 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 Thornhollow Rift:

ID	Name	Harvestable
FLORA-CRYS-020	Crystalweed	Yes
FLORA-TECT-020	Tectonmoss	Yes
FLORA-CRYS-020	Crystal Weed	No — Protected
FLORA-TECT-020	Tectomoss	No
FLORA-RIFT-020	Rift Spore	No
FLORA-SPIN-020	Spine Grass	No
FLORA-FISS-020	Fissure Bloom	No
FLORA-TECT-020	Tecton Root	Yes

Three 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 Crystal Weed, Tectomoss, Rift Spore, Spine Grass, and Fissure Bloom. The harvestable cell says No — Protected on Crystal Weed and No on Tectomoss, Rift Spore, Spine Grass, and Fissure Bloom. Both wordings are left as recorded.

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

Boss	Blightfang, Ancient of Biome 020
Difficulty	T3_Heroic
Recommended party	4
Damage type	Void
Arena	{'location': 'Root Hollow', 'description': "The boss encounter takes place in the heart of Thornhollow Rift's most extreme terrain feature. The arena is shaped by rift tectonic 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': 'Thorn-rift junction', 'hazard_active': 'Rift Thorn Impalement'}
Ground blurb	The Fault Prowler the Ancient is the apex expression of Thornhollow Rift's ecosystem — a creature that has been shaped by rift tectonic conditions across centuries of adaptation in 0.68g. It is not simply dangerous. It is what Thornhollow Rift would be if the biome could choose to fight.

Weather

The atmosphere row records weather patterns Thorn Mist, Root Rain, and Hollow. Those three names are not rows in the weather table. Six weather rows are recorded for this biome.

ID	Name	Code	Recorded effect
WX-020-STORM	Storm	STORM	Severe visibility reduction. Player movement restricted. Pack predators shelter. Ambush predators peak activity.
WX-020-ASH	Ashfall	ASH	Reduces visibility. Ash-adapted creatures +15% aggro. Node guardian activity increases. Rift Thorn Crystal harvest modified.
WX-020-SNOW	Cold Event	SNOW	Winter only. Fauna density minimum. Node guardians reduced patrol. Resource yield -20% all types.
WX-020-ANY	Any Weather	ANY	Weather-independent spawn — present in all conditions.
WX-020-RAIN	Rain/Mist	RAIN	Rare moisture event. Suppresses primary hazard temporarily. Most comfortable traversal conditions.
WX-020-CLEAR	Clear Sky	CLEAR	Maximum K3V amber light. Visibility maximum. Best navigation conditions. Standard resource yields.

Spawn entries recorded on those rows: Storm 12, Ashfall 11, Cold Event 16, Any Weather 11, Rain/Mist 13, Clear Sky 7. Night-multiplier entries above 2.0 recorded on those rows: Storm 1, Ashfall 1, Cold Event 3, Any Weather 1, Rain/Mist 4, Clear Sky 1.

The node-network file records a guardian name string on each of these eleven nodes. Those strings are not rows in the named mob list above. The biome file, used in this table, records no guardian on the four positive nodes and a guardian present on the seven 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 B020, followed by the ground description and settlement names already on this page.

Recorded overview prompt: ABERNON game concept art, Biome 020 Thornhollow Rift, K3V amber light, rift_tectonic environment, 0.68g low gravity, Riftwalker Brotherhood (VANISHED) 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 Thornhollow Rift, biome 020, rift tectonic, under K3V amber light at 0.68g. A broken rift of sunken wilds where roots protrude from every crack and the earth coils with hunger. The hollow was formed when a tectonic plate collapsed inward trapping an ancient forest beneath the surface. The roots still grow upward seeking light. Terrain recorded as thorn-rift junction, crystal impalement zone. Unstable ground. Crystal formations erupt and collapse. The fissures pulse with residual tectonic energy. Rift Thorn Impalement is the recorded primary hazard. Rift Thorn Crystal is the signature resource. Recorded colour palette: fractured grey, cyan en. The Riftwalker Brotherhood settlement Thornhollow Settlement is visible, with Root Hollow and Sunken Forest Rift 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, IMG00381 through IMG00400. Each uses this recorded stem, with the type name in place of the scene type: AAA game concept art, Thornhollow Rift, rift tectonic biome, [type], crystal formations, tectonic rifts, amber energy pulses, Rift Thorn Impalement environmental hazard visible, Unreal Engine 5 quality, painterly, cinematic lighting, amber K3V star palette, alien yet familiar world aesthetic.
