One of the mission roles for the Redemption in the Twelfth Fleet is diplomatic hence why there is a detachment of the Diplomatic Corps on board and I do have long-term plans in the plot.  I am a GM who does like to play plot close to the chest as I found it does lead to enjoyment and satisfaction to be pleasantly surprised.  That said I would never spring anything negative to your character without discussion and consent as I have had such happen to me and it was far from fun.  Also I am always open to questions and conversation.  I also promise all characters will have many "Big damn hero" moments in the story.
