Here is a d20 Hex-Crawl Terrain & Discovery Generator designed for running lost-world exploration campaigns in Pellucidar and the Prehistoric Inner Earth using Troll Lord Games’ Amazing Adventures RPG (SIEGE Engine).

Because Pellucidar features a perpetual noon-day sun suspended in the center of a hollow Earth, traditional navigation methods (like tracking solar movement or star positions) fail entirely. Use these tables to generate hex terrain, local environmental twists, primary features, and survival hazards on the fly.

1. Primary Terrain Type (d20)

When moving into an unmapped hex, roll a d20 to determine the dominant landscape.

d20	Terrain Type	Travel Pace	Key Feature / Aesthetic
1–3	Cycad Forest & Fern Jungle	Normal	Looming giant tree ferns, scale trees, dense undergrowth; high humidity.
4–6	Bioluminescent Fungal Marsh	Slow ($\frac{1}{2}$)	Spore-choked wetlands lit by giant glowing fungi and toxic bogs.
7–9	Volcanic Ash Plains	Fast	Crisscrossed by lava channels and active fumaroles; low cover.
10–12	Primeval Savanna & High Grass	Normal	10-foot-tall golden grass shielding megafauna and stalking predators.
13–14	Subterranean Shoreline / Inland Sea	Varies	Black sand beaches meeting tideless, sunlit oceans.
15–16	Petrified Forest & Crystal Uplands	Slow ($\frac{1}{2}$)	Ancient fossilized timber groves and jagged quartz ridges reflecting noon light.
17–18	Deep Abyss & Canyon Maze	Very Slow ($\frac{1}{4}$)	Massive tectonic chasms dropping down into pitch-black lower caverns.
19	Gravity-Defying Floating Peaks	Very Slow ($\frac{1}{4}$)	Upward magnetic anomalies causing suspended landmasses and waterfalls.
20	Inner World Desert (Red Dust Wastes)	Normal	Dry, baked clay plains exposed to the relentless central sun.

2. Inner Earth Environmental Modifier (d20)

Due to the lack of a day/night cycle, atmospheric conditions in the hollow Earth can shift rapidly based on subterranean vents and constant solar heat.

d20	Environmental Condition	SIEGE Engine Effect / Hazard
1–4	Stationary Noon Heat	Clear visibility. High risk of heat exhaustion (CON SIEGE Check daily or gain 1 level of Fatigue).
5–7	Heavy Spore Fog	Visually obscured beyond 30 feet. Ranged attacks suffer a -2 penalty; WIS SIEGE Check required to maintain direction.
8–10	Sudden Volcanic Ashfall	Choking dust clouds. Characters without cloth masks suffer 1d4 damage/hour from inhaled ash.
11–13	Geothermal Steam Venting	Scalding mist bursts across the hex. Spottable with a WIS (Survival) check, otherwise 1d6 fire damage.
14–16	Electro-Magnetic Storm	Charged particles from the central sun produce atmospheric lightning. Brass compasses and radio gear fail completely.
17–18	Subterranean Tremor	The inner shell shifts. Falling rock hazard in canyons or mudslides in jungle terrain (DEX SIEGE Check or 2d6 damage).
19	Toxic Sulfuric Updraft	Choking gas fills low-lying areas. CON SIEGE Check required every 4 hours or suffer -2 to all Attribute Checks.
20	Bioluminescent Night-Simulation	Heavy dense clouds block the central sun, casting the hex into eerie, dim blue bioluminescence for 1d6 hours.

3. Major Hex Discovery / Feature (d20)

Roll once per hex to discover points of interest, lost ruins, or faction strongholds.

d20	Hex Discovery	Description & Exploration Hook
1	Mahar Sun-Temple	A massive basalt structure dedicated to Mahar psychic research. Contains ancient reptilian scrolls and telepathic machinery.
2	Sagoth Slave Camp	A fortified timber stockade where Sagoth guards pen captured human (Gilak) tribesfolk before transport to Mahar cities.
3	Gilak Cliff Village	Primitive human settlement built high into cliff walls, accessible only by rope ladders. Suspicious of surface technology.
4	Korsar Pirate Haven	A palisade fort built on an inland sea cove by descendants of surface buccaneers. Equipped with old iron cannons and swivel guns.
5	Wrecked Surface Iron Mole	The rusted, steam-powered drilling machine of a previous surface expedition, buried half-way in a cliffside. Salvageable parts or logs.
6	Megafauna Nesting Grounds	Breeding territory for Ta-ho (Terror Birds) or Tarag (Saber-tooths). Rich in ivory/pelts, but highly dangerous.
7	Tar Pit & Bone Graveyard	Bubbling asphalt lake holding thousands of prehistoric skeletons. Valuable for rare materials and preserved fossils, but a sinkhole hazard.
8	Bioluminescent Cave System	Entrance leading to cool subterranean caverns beneath the inner surface, bypassing the relentless heat of the central sun.
9	Abandoned Prospector Outpost	Built by a 19th-century explorer who succumbed to "Noon Madness." Contains a partially completed map of the surrounding hexes.
10	Petrified Titan Tree	A hollowed-out fossilized giant tree serving as a neutral trading post between rival Gilak tribes.
11	Active Geyser Field	Mineral-rich hot springs capable of curing disease or fatigue, guarded by territorial Tandor (Mammoths).
12	Obsidian Quarry	Controlled by a militaristic human tribe crafting high-quality weapons. High trade value for steel or iron tools from the surface.
13	Monolith of the Outer Gods	An ancient, pre-human stone spire etched with non-Euclidean runes that hums with psychic energy (CHA SIEGE Check or temporary insanity).
14	Subterranean Waterfalls	A massive river plummeting into an bottomless abyss. A potential river-barge travel route or severe navigation hazard.
15	Carnivorous Plant Grove	Dense patch of sprawling tendril-vines (Sithic flora) that attempt to grapple and drag explorers into digestive pods.
16	Floating Island Anchor Point	Thick, petrified vine ropes anchoring a floating mesa to the ground. A tribe of primitive humans lives on the floating island above.
17	Fossilized Mahar Citadel	Ruined city of the reptilian overlords, now overrun by wild beasts and scavengers. High risk, high reward for ancient tech.
18	Downed Surface Aircraft / Balloon	The wreckage of an early 20th-century aviator or airship expedition. Holds surviving rations, firearms, or nautical equipment.
19	Natural Magnetic Nexus	Metal objects are pulled toward a central iron-rich mountain spire, making heavy steel armor or weapons unwieldy (-2 to hit).
20	Dimensional Anomaly / Gate	A shimmering spatial fissure that periodically opens to the surface world (e.g., Sahara Desert) or Mars (Barsoom).

4. Inner Earth Navigation Rules (Amazing Adventures)

When exploring unmapped terrain without a fixed day/night cycle, use the following rules to keep track of party fatigue and direction:

1. Noon Madness & Time Tracking: Without a night sky, characters must track time using mechanical watches or internal rhythm. Every 24 hours of travel without rest requires a CON Check (CL equal to days awake). Failure inflicts 1 level of Exhaustion and a -2 penalty to WIS Checks.

2. Getting Lost (WIS Check): The Party Leader/Guide must make a WIS (Survival/Navigation) Check when entering a new hex.

   • Base CL: 0 for Savanna/Plains, +2 for Cycad Jungle/Marshes, +4 for Canyons/Floating Peaks.

   • Failure: The party strays into an adjacent, unintended hex and loses 1d4 hours of travel time.

3. Random Encounters: Roll a d6 once per hex entered or every 8 hours spent resting:

   • 1: Wild Prehistoric Beast (e.g., Tarag, Gorgosaurus, Tandor)

   • 2: Faction Patrol (Mahar/Sagoth raiders, Korsar pirates, or Gilak hunters)

   • 3: Hazard / Environmental Hazard

   • 4–6: No Encounter
