Derelict — RSV Halcyon Verge

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 — RSV Halcyon Verge, a derelict freighter deck plan in blueprint style with hull breaches, numbered rooms and doors

Generate a derelict freighter in the free editor

RSV Halcyon Verge is under quarantine, by its own crew, in the end by whoever was left. Something came aboard in a cargo lot and moved through the ship in days. Medbay is sealed. There are marks on the doors, from the inside.

Last log entry: Tech Adeyemi.

Hook: The beacon says WARN OFF. Somebody switched it back to MAYDAY an hour ago.

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

Cold. Frost on every surface. Viewports forward. Someone scratched a tally into the frame.

Log fragment (Cpt.) "Set the beacon to WARN OFF. If a ship answers anyway, they were warned."

2 Crew quarters

Two bunks stripped; nobody says why.

Hazard one bunk is still occupied and the occupant is still warm.

3 Galley

Dark. Emergency lighting only. Long table. Someone always leaves a mug out.

Log fragment, scratched into the table "we kept it out of the galley for nine days"

4 Medbay

Runs on battery. Something was treated here recently.

Salvage full trauma kit, sealed, and a case of broad-spectrum antivirals that did not work.

5 Cargo hold

Ladder down. Crates torn open from inside.

Log fragment (Deckhand) "Lot 14 was breathing when we loaded it. Told the XO. XO said crates don't breathe."

6 Cargo hold

Ladder down. Crates torn open from inside.

Salvage forty crates. Lot 14 is open. The others are worth a fortune to someone who does not ask where they came from.

7 Engineering

Reactor hums. The engineer sleeps here.

8 Lab

Sample cases, a sealed cabinet, a log nobody finished.

9 Escape pods

Something moved in here — recently. All pods gone.

10 Life support

Dark. Emergency lighting only. Scrubbers and water reclaim. Pump 2 knocks.

11 Hangar

Empty cradle. Scorch marks.

12 Drive section

Main engines. Loud, hot, hostile.

Connections:

- Ladder at column 8, row 3 → Lower deck

Lower deck

1 Cargo hold

Sealed containers. The manifest says "agricultural".

2 Life support

Something moved in here — recently. Scrubbers and water reclaim. Pump 2 knocks.

Hazard bodies, arranged. Someone took care over this. Disturb them and the air changes.

3 Escape pods

All pods gone.

4 Engineering

Reactor hums. The engineer sleeps here.

5 Lab

Something moved in here — recently. Sample cases, a sealed cabinet, a log nobody finished.

Hazard broken sample cases. The floor is wet and it is not water.

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.
