ISV Juniper 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 Reyes. Their trail runs through three rooms. Hook: A buyer is already paying for Lot 14, sight unseen, and will pay more for silence.

Free, CC0. The .dd2vtt carries walls, doors and 4 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.
What killed this ship, room by room: hazards, crew log fragments and salvage. Players get the map, you get this.
Consoles dark. One chair is turned to face the door.
Hazard bodies, arranged. Someone took care over this. Disturb them and a grey dust lifts into the air: anyone unfiltered rolls against the contagion.
Log fragment (Cpt.) "Set the beacon to WARN OFF. If anyone docks anyway, they were warned."
Rack half empty. The sign-out sheet stops mid-line.
One sample tray labelled and signed. The rest are blank.
Hazard broken sample cases. The floor is wet and it is not water. It soaks through boots: anyone who walks through it rolls against the contagion.
Salvage the doctor's notes, complete, on a data slate. They end mid-sentence.
Battery light blinking. The last treatment is still on the screen.
Hazard contagion. The isolation field failed with the power. Anyone who breathes here unfiltered rolls against it, and a failure is the fever that comes before the calm.
Log fragment (Dr.) "Fever, then the calm. The calm is the dangerous part. Adeyemi was fine at breakfast."
Salvage full trauma kit, sealed, and a case of broad-spectrum antivirals that did not work.
Trail 2/3 The other end of the line. Reyes's helmet sits under the handset, and on the bulkhead beside it, chalked in Reyes's hand, the next room: the drive section (7).
Panels off, parts sorted on the deck by someone who ran out of time.
Lockers open. Whatever was worth taking has been taken.
Hazard one bunk is still occupied and the occupant is still warm. They are calm, and they reach for the nearest hand: a touch is a roll against the contagion.
Log fragment (XO) "Kowalczyk is calm now. I have locked her in. I have told her it is for the fever."
Trail 1/3 A sound-powered handset hanging off its hook, the line still open to the medbay (4). It needs no power, and someone at the other end kept talking long after anyone answered.
Cold. The torch has not fired in weeks.
Trail 3/3 Reyes's last call went here. The recorder clipped under the console is Tech Reyes's. It caught both ends of the call, and everything after, to the end of the last day.
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.
