Delverium Biomes

Delverium does not ship a tourist brochure of named regions. Sagestone Games generates a 2D survival world, then asks you to farm it, fish it, and delve it while a corruption called the Faults sits in the background like a dare. Steam’s own copy is the whole official atlas: exotic biomes, hidden caves, and dangerous dungeons. This unofficial page will not invent titles the studio has not printed. It will describe what the demo, previews, and Steam screenshots actually show: a surface homestead, forest combat, glowing caves, lava depths, and ice-looking underground.

Early Access is scheduled for September 22, 2026 (the storefront may show September 21). The free demo has been on Steam since February 2025 and covers starting biomes plus early dungeons. Extra biomes belong to the paid build and to the years after unlock. When a palette on your seed does not match a screenshot, believe your seed.

The embedded Nookrium session is a look at the open-world homestead — trees, water, a box of walls — not a finished 1.0 documentary. Watch it for how the starting land feels to walk, then use the sections below as a field guide rather than a map with pins.

Surface homestead: plains, trees, and water

You spawn in a wide starting band: grass, mixed trees, stone, and enough water to make you plan a house instead of a tent. Official screenshots and demo footage agree on the mood. Stone and wood rooms sit beside tilled plots, fences, livestock, and a pond or river. Palms show up near water in several shots. Autumn-orange canopies mix with ordinary green. None of that is a named “Palm Coast DLC.” It is the starting overworld doing its job: give you wood, straw, stone, a place to till, and a reason to close a door before night.

Build here first. Night zombies and bats do not care that the river is pretty. A valid room (walls, door, bed, light) belongs on this grass, not in the first cave you find. Farming wants a hoe and a watering can next to that door. Fishing wants the water you already live beside once the Early Access rod exists; the short demo still omits that loop. Do not walk until the music changes on hour one. The first death in this game is usually “I wanted to see the coast,” not a boss.

The coast is real in previews: lakes, ocean edges, and the goblins who treat interesting ore as bait. Take a little copper, go home, smelt later. The homestead is the biome you are allowed to be greedy in. Everything else is a commute.

Forest combat

Steam shots and demo recordings show denser tree cover away from the starter lawn: tight trunks, yellow-topped stands, and the kind of undergrowth that hides a wasp until you open the inventory. This is still the overworld, not a separate planet. Treat it as forest combat — the place where a hoe is the wrong hotbar slot and a real weapon is not optional.

Keep a torch even on the surface when the canopy eats the clock. Keep food. If a pack of goblins or wasps starts stacking, you are not “in the wrong named biome.” You are under-geared in the woods. Go home. The dungeons rules (light, pickaxe, cooked stack) apply the moment the trees stop being a lumber pile and start being a fight.

A 2025 roadmap note mentioned swamp vegetation and labyrinth dressing as art work. Those are production bullets, not an invitation to label your seed Swamp Biome #3. If your world grows reeds or a twistier cave mouth after an art pass, describe what you see. Do not promote a dressing pass into a fake atlas entry.

Caves and glowing stone

The other half of the pitch is underground. Hidden caves open from the overworld; you mine walls, place torches, and decide whether tonight is ore or retreat. Demo players meet zombies, bats, goblins, ghosts, wasps, and spectres long before they meet a palette that looks like a postcard.

Steam screenshots go further than the starting hole. One common still shows glowing caves: teal or cyan water, ice-like spikes, mushrooms, placed torches, and magic shots in the dark. Another still shows ice-looking underground — pale stone, cold palette, the same need for light. This wiki will call those glowing caves and ice-looking depths because that is what the pixels are. It will not name them Crystal Hollows or Frostmarch.

Rules do not change because the water is pretty:

• Place torches. Holding a light is not a map.
• Mine a vein and an escape, then stop. Every extra hole is a new angle for wasps.
• Pack cooked food. Raw forage is how preview writers described walking back from a shrine.
• Activate Journey shrines when you pass them so the walk home is not the whole evening.

If the pack turns supernatural and you are still in starter gear, leave. Curiosity is the content. Under-levelled curiosity is a corpse at a shrine.

Lava depths

Official screenshots also show lava depths: red lakes, orange undergrowth, dark stone, and combat beside heat you would not farm next to. Store art and in-game stills put a player on a narrow bank while blue shots cross the lava. That is a later underground look, not a starter lawn. Do not assume the free demo’s one-to-two-hour slice contains every lava room on the Steam page. Extra biomes are on the Early Access and 1.0 list.

When you do see red:

• Treat lava as a floor you do not test with your face. This page will not invent burn numbers.
• Keep ranged options if the arena is a thin bank. Melee still matters in doorways.
• The first boss gear check (torches, food, melee and ranged) is the same checklist with worse lighting.
• Come home. Water the farm. The lava will still be there after you cook.

Faults, mystery, and what not to name

Steam’s story hook is short on purpose:

• A great peril is infecting the land.
• You uncover lost fragments of lore.
• You hunt the invading Faults to piece together Delverium’s hidden truth.

That is a mystery structure, not a biome label you stamp on a red tile. If a cave feels wrong in a way that is not just bats — a shift in palette, a density of ghosts, a structure that does not look like a mine — mark it and return with better kit. This fan site will not tell you the Faults “are really X.” When Sagestone ships more story during the up-to-two-year Early Access window, new official language belongs in updates, not in a fake region name on this page.

How to use a procedural map

1. Close a homestead on the starting grass. Farming first, then a short walk.
2. Fish the water you already live next to once the rod exists — see fishing — instead of hiking to a postcard coast.
3. Light the first cave from dungeons. Place torches. Bring food.
4. Touch shrines so biome hops are fast travel, not a death march.
5. Only then push glowing caves, ice-looking stone, or lava depths, and only then take an early boss door seriously.

Co-op does not change the generator. Solo, 4-player split-screen, and 8-player online share one seed on the host PC while that player has the game open. There is no official dedicated server. Assign the forest and the farm so four people are not chopping the same tree while nobody watches the cave mouth.

Sagestone’s 1.0 language is “more biomes,” not a list you can spoil. June 2026 notes promised additional world content and left it unspoiled. This page will stay visual on purpose: surface homestead, forest combat, glowing caves, lava depths, ice-looking underground, and a Faults mystery you hunt without a wiki ending. When the palette changes, you have gone far enough to write your own notes. When it has not, you still have a house to water.
