Drengr's goal is to become the best Inquisitor Vader ever had. He will try to achieve that goal, no matter how many Jedi he has to kill or what sacrifices he has to make but perhaps a different path awaits him.
After the defeat at the Battle of Yavin, Vader jumps into hyperspace, only for himself to be taken into the JLU universe by accident. Free from Sidious's servitude and from the Galactic Civil War, he forges an empire in the Milky Way Galaxy while searching for who he is. That's, of course, if he can escape the mad woman known as Queen Maxima, who is trying to be his loving wife.
