If you want to save this fragile galaxy, relying only on yourself will not be enough. Heroes will never be alone. There are many like-minded people in this galaxy. Find them and form a powerful alliance!
In any corner of the galaxy, it is possible to meet all kinds of interesting people and interact with them in a variety of ways, such as trading, dating, gifting, robbing, and holding captive, so as to make friends or establish enemies. When a relationship is good, they can be incorporated into your own force, as subordinates or vassals that command their own troops. When a relationship sours, you might be hated, or even hunted, even if you are light-years apart.
If your heart gets captured by someone you meet, it is ok to fall in love with them, get married, have children, and spend the rest of your life together. Your children might grow up to become the strongest leaders of your burgeoning faction.
