What system is this designed for?
Traveller

What are the necessary assumptions of your adventure?
Traveller assumes no communication faster than travel. Travel of 1 to 6 parsecs (depending on ship type) will always take about a week. Anti-gravity is common, AI rare, and Humans have populated the stars – but so have a wide variety of alien races, including uplifted canine aliens called Vargr. They are a colourful, somewhat chaotic race who rate charisma as important rather than social standing and inhabit the coreward sectors of Charted Space. Planets may be at various stages of technological development and are generally ruled by their own governments. Nobility, psionic powers, Ancient progenitors, robots and life-extending anagathic drugs may or may not exist but are not germane to this adventure unless the Referee introduces them.

This adventure assumes a Vargr protagonist (one is provided but your own PC could be used instead as long as the PC is on the run from various factions), Charted Space and a copy of the Core Rulebook for Traveller (other editions may easily be used). Access to Aliens of Charted Space: Volume 1 (which was used to create Dhoukhi and provides additional information on the Vargr race) and travellermap.com may be useful but are not required. Mention of the ‘Chases’ mechanic by Michael Brown in Burst Transmissions, vol.1 or Burst Transmissions Compendium is made and can be used but isn’t absolutely required. The nature of the Vargr race has tended to splinter any interstellar government into various polities and one of these, the Glory of Taarskoerzn, sets the scene for this adventure. Library data exists here: https://wiki.travellerrpg.com/Glory_of_Taarskoerzn but the Referee can make as much or as little of that as required.

Is there any sensitive content in this adventure?
Mention is made of slavery but does not need to form a major part of the adventure and the slavers could be replaced with ‘prison guards’.
