A design house responsible for a number of Traveller products published by Comstar Games. Co-owned by Martin J Dougherty and William Andersen of Comstar Games.
from the front matter of an Avenger Enterprises publication:
Avenger Enterprises is a loose collection of semirandom individuals who have seen fit to involve themselves in producing Traveller materials. Or if you prefer, Avenger Enterprises is a design house coowned by Martin J Dougherty and William Andersen of Comstar Games, representing some of the finest Traveller and RPG writing talent worldwide.
Avenger’s writers have written and edited Traveller materials for publication since 1994, and have an involvement in the games industry stretching back a decade more. Avenger people (using the term ‘people’ very loosely) have written, edited and otherwise freelanced for many other game systems and for publishers including Mongoose Publishing, GDW, FASA, Imperium Games, Steve Jackson Games, Hekaforge Productions and PBM Scroll Magazine. Most relevant to this adventure; Avenger staff were heavily involved in the production of the Mongoose Traveller Spinward Marches sourcebook.
Note that Avenger is not a publisher but a design house. All Avenger Enterprises products are published by Comstar Games, through the Flaming Cobra imprint of Mongoose Publishing.
