A Rift in Time by Joseph Mohr is a role playing game supplement published by Old School Role Playing for use with Cepheus Engine. As such, it is covered by the Open Game License and some parts are considered to be Open Game Content as a result.
The supplement is available as a 14 page Pay What You Want PDF from DriveThruRPG. Two pages are the front and rear covers, three the front matter and three the Open Game License.
The opening paragraphs explain that the Sonora Sector – the adventure is set in the Frontiers of Space, though this isn’t stated – has been plagued by chaotic natural occurrences. Including the sudden appearance of black holes, which seems rather extreme. It’s also been reported that similar things are happening in other sectors. The characters are hired by a scientist who believes that what’s happening is the result of time travel, and what’s the characters to stop it.

A Rift in Time in Review
The PDF lacks bookmarks and has enough different sections that these would have been useful. Navigation could be better. The text maintains a single column format and some minor errors were noticed. Bar the covers, there are no illustrations. Presentation is adequate.
Perhaps the biggest problem with the adventure as written is that the time machine can cause major changes to the setting, and it doesn’t appear that these are undone if the machine is destroyed. It will probably be a good idea for the GM to address this in some way before running it, unless they want to have entire governments vanish and black holes appear out of nowhere. Other than that, the adventure is a little different. A Rift in Time can be found by clicking here.
