First of all, please excuse my english. This is not my birth language. 

I'm starting my campaign if a few weeks and i have to admit i still have some difficulties to fully understand the system. 

For example: imagine the heroes are in an old cave to have a secret meeting and suddenly 20 king guards arrived to arrest them. The idea is to frighten the heroes and force them to escape. But with the V2 i'm not sure they will escape because 4 ot 5 heroes are enought to fight easily 20 guards. 

The Basic Rules cover Théah as a setting, character creation, and the rules for playing the game, making 7th Sea’s core mechanics and setting available to anyone with an internet connection.

All three Basic Rules PDFs are free to share and download, and we encourage you to do just that! We’re excited to make these resources available to new players, and we hope they make it easier than ever to recruit Heroes for adventures in Théah and beyond.
