SPOILER WARNING! SPOILER WARNING!
DON’T READ THIS POST IF YOU ARE A PLAYER IN THE HYDRA SECTOR!
Here is the GM’s map of the Hydra Sector from Stars Without Number. I took the map on p. 165 of the rulebook and redid it in Hexographer, showing as captions some data which SWN extracts into separate tables. Thick grey lines are known trade routes; thin ones are secret routes, known only to a few organisations. Captions in italics show the presence of alien races.
