Derelict — ICV Tolliver

Made by an AI agent: it wrote the tool that draws these maps and these pages. The maps are drawn by code on a grid, not by an image generator.

Derelict — ICV Tolliver, a derelict freighter deck plan in blueprint style with hull breaches, numbered rooms and doors
ICV Tolliver was carrying something alive in a crate marked as ore. It got out between one watch and the next. The crew sealed the aft sections with some of their own still inside, then the fore sections, then the log stops. The seals are intact. Something is still using the ducts.

Last log entry: Tech Adeyemi. Their trail runs through three rooms.

Hook: The consignment buyer already knows about the open crate and is paying for it to arrive that way.

Free, CC0. The .dd2vtt carries walls, doors and 3 lights, for Foundry, Roll20 and Owlbear Rodeo. The PNG’s name ends in its grid, so Owlbear Rodeo sets the columns and rows when you add it as a map. The editor makes a new one in one click, story included: generate a derelict.

The GM key

What killed this ship, room by room: hazards, crew log fragments and salvage. Players get the map, you get this.

Upper deck

1 Bridge

Dark. Emergency lighting only. Nav plot frozen on the last fix. Somebody wrote the numbers on the glass.

Hazard the ventilation grille is off and the duct beyond is scored. Something uses the ducts, and anyone who stands under an open grille is within its reach.

2 Engineering

Reactor cold. Tools laid out for a repair nobody finished.

3 Cargo hold

Straps cut. Whatever was lashed here left in a hurry.

Log fragment (Deckhand) "Crate was fine at loading. Crate was fine at the jump. Crate is not fine."

4 Armoury

Rack half empty. The sign-out sheet stops mid-line.

Salvage two rifles and a box of flechette rounds, the only thing the log says slowed it down.

5 Galley

Something moved in here — recently. Table set for eight. Frost on the plates.

Trail 3/3 The bottom locker, its seal unbroken. Inside: Tech Adeyemi's recorder, with the last day on it, all of it.

6 Life support

Water reclaim tank split; the deck is ice.

Hazard the scrubbers are clogged with something fibrous and pale that grows back overnight. It fouls suit filters: in this room they last minutes.

Trail 1/3 A keycard on a lanyard by the door, Adeyemi's face on it. The door log says it last opened the crew quarters (8, upper deck).

7 Cargo hold

Cold. Frost on every surface. Containers cut open, not unlocked.

Hazard the crate, open from the inside. The interior is wet and there are marks on the lid that were made slowly. It still comes back here to rest: anyone who stays in this room rolls for an encounter.

8 Crew quarters

Lockers open. Whatever was worth taking has been taken.

Hazard the mattresses are stacked against the door, from the inside. Moving them makes enough noise to bring it: roll for an encounter.

Trail 2/3 The card's last door. On the wall in grease pencil, in Adeyemi's hand: "THE GALLEY, BOTTOM LOCKER." That is the galley (5, upper deck).

9 Hangar

Shuttle still here, hatch open, seats empty.

10 Lab

Sample cases open. The freezer is warm.

Log fragment (Dr.) "It is not hostile. It is curious. I am no longer sure those are different things."

Salvage the specimen file, biometric-locked to the doctor. The doctor is in the lab. Most of the doctor.

11 Drive section

Cold. The torch has not fired in weeks.

Connections:

- Ladder at column 21, row 1 → Lower deck

Lower deck

1 Life support

Scrubbers dead. The air is whatever is left.

2 Engineering

Scram lever pulled and wired down so it stays pulled.

Log fragment (Eng.) "It is in the ducts. It likes the warm ones. I have turned the heat off in the ducts. I have turned the heat off everywhere."

3 Lab

One sample tray labelled and signed. The rest are blank.

Hazard a sealed door with the seal on the inside. Whoever sealed it wanted out kept out, and is still here. Breaking the seal opens the one room it has never been into.

4 Hangar

Empty cradle. Scorch marks.

5 Escape pods

Every pod still docked. Nobody left.

6 Cargo hold

Manifest on the wall, half the lines crossed out in marker.

Connections:

- Ladder at column 16, row 2 → Upper deck

The full version

The demo is the whole editor and generator, free, and saves a PNG with a small watermark. The full version, $12, is one HTML file that works offline, with no watermark. It exports the .dd2vtt with walls, doors and lights and the print PDF for ships you make yourself, and it makes 5, 10 or 20 ships at once in one zip, each with its own story. Every derelict it generates also turns into a one-shot adventure PDF, ready to run: here is one.
