A Review of the Role Playing Game Supplement Intervention

Intervention 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 17 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 belters have made an important strike in an asteroid belt. However, a creature emerged from the asteroid in a space ship and has been causing havoc, killing hundreds. The characters are hired by the company that is the primary claim holder on the asteroid to deal with the problem.

Patron gives details on the company representative.

Complications are things that can go wrong in the adventure, or which are not known. The primary issue is that the creature, called the Lenkar, is the last survivor of a very technologically advanced, and extremely hard to kill, alien species that used to call the asteroid home.

Asteroid X-762 in the Hohosarsyia Field gives details on the asteroid, and the complex inside it that the Lenkar calls home.

The Lenkar gives stats and details on the creature.

A Team of Angry Miners has stats on some miners who are seeking revenge.

A Deal Could Be Struck explains how the Lenkar would be willing to deal with the miners.

Possible Outcomes has some ways of resolving the adventure.

Game Master Note explains that using brute force could end badly.

Mission Completion Objectives is simply to resolve the situation any way possible.

The final page of content has a map of the asteroid’s interior.

Intervention 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. Apart from the black and white map and the cover there are no illustrations. Presentation is adequate.

This is a potentially dangerous adventure, given that the Lenkar has technology far in advance of anything the characters can lay their hands on. Violence, which is commonly used as a first step, can turn out really badly. Though it’s rather odd that the Lenkar’s species apparently inhabited an asteroid, rather than a planet that would in fact be big enough to support them. Intervention is an okay adventure and it can be found by clicking here.
