As an Action, you may build a Bridge for 2 Workers. (You may take this Action any number of times during a round. You may still build Bridges via the respective Power action.)
After building the Stronghold, each round when passing, get 3 Victory points for each Bridge connecting two of your Structures.
The Engineers' faction board
Initially, Engineers have been a mountain tribe living in inaccessible valleys and ravines. They have learned how to build bridges and mountain roads to keep their remote settlements connected. They enjoy dominating nature by means of technology. They appear eccentric to the other factions when poring over their construction plans.
