From the rear cover:
This adventure is suitable for use with all forms of Traveller, in particular Marc Miller's Traveller and Steve Jackson's GURPS Traveller.
Imperial Vargr…
…uplifited doggies who do the dirty jobs. They are the underclass, doomed to die in the slums.
Little Heaven…
…is a small colony beseiged by murderous pirates. They need help - and they don't care if you've got fur and fangs if you can fight! Saving the colonists is only the first step - the struggle continues all the way to the Imperial Court.
A detailed Traveller adventure…
…containing pregenerated Vargr characters, deckplans and statistics for two starships, a description of the colony of Little Heaven, non-player characters, guidance on playing Vargr and a generic task system compatible with all versions of Traveller.
