Derelict — ICV Merlin

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 Merlin, a derelict corvette deck plan in blueprint style with hull breaches, numbered rooms and doors

Open it in the free editor

ICV Merlin is still warm aft. The reactor tripped, the coolant loop failed a day later, and the engineer sealed the drive section with herself inside it. The rest of the crew waited at the mid-frame door for word. The word never came, and neither did the rescue.

Last log entry: Cpl. Petrov. Their trail runs through three rooms.

Hook: The engineer's last message went to a private address, not the company. Someone off-ship knew first.

Free, CC0. The .dd2vtt carries walls, doors and 2 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.

Main deck

1 Bridge

Nav plot frozen on the last fix. Somebody wrote the numbers on the glass.

2 Medbay

Dark. Emergency lighting only. Autodoc stopped mid-cycle. The patient is not in it.

Log fragment (Dr.) "Dosages are past what the manual covers. Giving what I have to whoever asks. Nobody is asking anymore."

Trail 1/3 Chalk marks on the door frame, Petrov's tally of the days. Below the last mark, an arrow and two words: "the hangar (7)".

3 Engineering

Panels off, parts sorted on the deck by someone who ran out of time.

Hazard coolant fog. Corrosive, heavier than air, pooled knee-deep. Suits last minutes, skin does not.

Salvage the spare coolant loop, still crated. Never fitted. Somebody will want to know why.

4 Lab

Sample cases open. The freezer is warm.

Salvage a case of unlabelled sample vials, refrigeration failed weeks ago.

Trail 3/3 The arrows stop here. Cpl. Petrov's recorder is wedged behind a pipe where nobody passing would see it. It holds the last day, start to finish.

5 Crew quarters

Something moved in here — recently. Lockers open. Whatever was worth taking has been taken.

Hazard deck plating hot enough to blister through boots. Something below is still cooking.

Log fragment, on a bunk wall in marker "DAY 6. WARM AGAIN. DON'T OPEN AFT."

6 Galley

Vacuum. Suit up. Table set for six. Frost on the plates.

Hazard the bulkhead door is welded shut from the far side. Cutting through takes time, light and noise: roll for an encounter when they start.

Log fragment (Cook) "Fed everyone at the mid-frame door. Eng. did not come forward for hers. Left it by the seal."

Way in only across the breach. The way that led here went with the hull, so getting in means crossing open space.

7 Hangar

Empty cradle. Scorch marks.

Trail 2/3 More chalk. Petrov slept here at least one night: a bedroll, ration wrappers, and the same arrow, pointing to the lab (4).

8 Drive section

The torch has not fired in weeks, and the deck is still warm underfoot.

Hazard radiation. Dosimeters climb fast here: every minute in this room is a dose.

Hazard the door is sealed, and the seal is still good. Breaking it takes time and noise, and lets out the heat behind it: roll for an encounter when they start.

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.
