After way too long doing character generation, we finally had our first full session of our Star Trek GUMSHOE game. They beamed down to a planet with a uncharted settlement made of Cardassian ship parts, hit a patch of interference, got scattered across the settlement valley, talked to some Bajorans and got an earful about mysterious Cardassian attackers nearby, which are connected (the Bajorans think) to the recently-occurring power drains.
