Derelict — ISV Corvid

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 — ISV Corvid, a derelict freighter deck plan in blueprint style with hull breaches, numbered rooms and doors

Open it in the free editor

ISV Corvid misjumped. The drive fired with the nav plot half-loaded and the ship came out somewhere with no stars in the right places. The crew rationed, then argued, then stopped. The drive is cold. The plot is still half-loaded.

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

Hook: Tamura's suggestion about what comes after a third is written down, and it was carried out.

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

Vacuum. Suit up. Consoles dark. One chair is turned to face the door.

Salvage the nav core, holding a jump plot no charts contain. Worth a career to the right astrogator.

2 Crew quarters

Lockers open. Whatever was worth taking has been taken.

Hazard a crewmember's tally scratched into every surface. Stare too long and you lose your own count.

3 Galley

Table set for six. Frost on the plates.

Hazard the ration printer was run on anything that fit. Whatever it printed last is still in the tray.

Log fragment (Cpt.) "Rations to half. Then to a third. Tamura suggested what comes after a third. I dismissed him."

4 Medbay

Dark. Emergency lighting only. Battery light blinking. The last treatment is still on the screen.

5 Cargo hold

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

6 Cargo hold

Containers cut open, not unlocked.

Salvage intact cargo, untouched; the crew were too disciplined, or too frightened, to open it.

7 Engineering

Scram lever pulled and wired down so it stays pulled.

8 Lab

Sample cases open. The freezer is warm.

Trail 1/3 Tech Okafor's slate, screen cracked. The last entry: "Going to life support (2, lower deck). Back in ten." Nothing after it.

9 Escape pods

All pods gone. Empty cradles.

10 Life support

New filters stacked by the door, still in their wrap.

11 Hangar

Shuttle still here, hatch open, seats empty.

12 Drive section

Fuel gauges at zero. The log says they were not.

Hazard the drive core is cold but not empty. Charge is bleeding off as static; metal tools jump in your hand.

Log fragment (Eng.) "The core will fire once more. Once. Either we pick a direction or the ship does."

Lower deck

1 Cargo hold

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

Trail 3/3 The code from the last room opens the locker here. Inside, Okafor's own recording of the last day. It is the first account aboard from someone who was there.

2 Life support

Scrubbers dead. The air is whatever is left.

Trail 2/3 Okafor got this far. One set of boot prints in the dust, heading for the cargo hold (1, lower deck), and a door code scratched into the frame.

3 Escape pods

Empty cradles, same as the other bay.

Log fragment (pod panel) four pods launched, four headings, none of them toward anything.

4 Engineering

Something moved in here — recently. Reactor cold. Tools laid out for a repair nobody finished.

5 Lab

The notes stop mid-word. The pen is on the floor.

Connections:

- Ladder at column 13, 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.
