Somnium Void - USR Space Opera Setting

Watermarked PDF
Suggested Price $1.00

One hundred billion citizens of the galaxy all saw it. The vision flashed before them for mere seconds, but what they saw stuck with them ever since. A black ship over a white moon. This seemingly innocuous image became burnt onto the brain of every man, woman and child across the galaxy. The event became known as the Somnium. Life would never be the same again.

Welcome to Somnium Void, a space opera campaign setting for Unbelievably Simple Roleplaying (USR). This pay what you want book contains rules and ideas for running a space opera game in a fun setting inspired by Star Wars, Star Trek and Firefly.

What Does a Game of Somnium Void Look Like?

A panicked human diplomat staggers down a dark street in Primum, a poison dart stuck in her side. She collapses on the road as a shadowy member of the Pale Kings melts into the darkness.

A Shade doctor wraps bandages around the bloody stump of a soldier on board a warship that is being bombarded by Novorian Skyweavers.

A Cthoni Somnium Guardian sinks her blade into the neck of a Sketh Warmaster as it releases its final death howl.

A Wulfen smuggler is boarded by Magnan security, knowing that they will find the contraband hidden away in the ship.

Somnium Void is a game of adventure and heroism in the far future. Players will travel to different worlds like the ashen Hollow and the cyberpunk planet of Zero, making allies, enemies and credits. All the while the great powers that be are locked into a paranoid struggle that will likely pull the players into a story of intrigue and war. Whether you want to play a game that's all about exploring new worlds and fighting aliens or whether you would prefer to get involved in politics and strategy, Somnium Void can be played in different ways. There is no one true way to play. Players can take on the role of smugglers, diplomats, assassins, Somnium Guardians, technopriests and more - the only limit is the imagination.

Looking over this right now. I like the setting here. I wish there was artwork for each race, allies & villains but I guess that leaves more to the imagination. Looking forward to trying this out.

Agreed. I just came back to this one after seeing a post about Tequendria going missing. Hopefully Scott has some time to update this one.

Is this compatible with USR 2.0?

Yes, it is. There's not much difference between USR 1 & 2. Combat specialisms were added and the optional Narrative Points. Otherwise the rest of the new stuff is just additional explanations of concepts IIRC.

Looks interesting, but the preview shows nothing useful about the game at all, so I'm not tempted to look any further.

This looks really nice. Can I suggest a more compact layout? Less blank chapter heading pages and single-column tables taking up a whole page? It does making printing less of a viable option.

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
