from the back of the book;
Tapani sector is the home of the rich and dangerous —-- of mighty lords, Imperial diplomats, and powerful Mining Guild officials. The big boys don't play nice, and what you don't know can hurt you. If you're going to be spending time in Tapani sector, you need to know the ins and outs of dealing with the Tapani nobility, and where to be seen when capital season rolls around. Learn when a Herglic merchant is insulting you, and where the best music festivals in the Freeworlds can be found. Most importantly, know which noble houses you can work with, and which ones are most likely to stab you in the back.
The Player's Guide to Tapani gives you this sort of information. It also provides everything you need to create characters thoroughly grounded in the sector: a gazetteer of major homeworlds, essays on the aliens common to the sector (and how they're treated by the humans), and a Heroes and Rogues-style character generation system which gives your character a history and background.
