I'm not sure about this either. It's nice, but... I have to agree with the Guv in saying that your main character stays the same guy he has been for 200+ years, with the same stuff happening to him. He only ever seems to be involved in battles, and his final scene her is also about him being the training officer for combat.
Give the guy something else to so, willya?

On the characters' End of Days, I have Andrew retire as an Admiral in charge of Yard Operations (a position seen on various ships' dedication plaques) since I'm such a ship nut and I'm working all that stuff out anyway. My adventures continue into the Next Generation with "my" granddaughter Karen.
I remember Jaeih telling me about the death of Andrea Yushikara. She heard Dido's song 'White Flag' and was inspired with a scene from the lines of the chorus. Which I've just looked up and will paste for you below:
But I will go down with this ship
And I won't put my hands up and surrender
There will be no white flag above my door
I'm in love and always will be
She envisions Andie, who still doesn't like Klingons, nonetheless performing a figurative "
Kahlesste kaase". From John M. Ford's book
'The Final Reflection' and used again on Peter Morwood's
'Rules of Engagement', it is an oath referring to the story of the Emperor Kahless, who died with his hand tied to the controls of his ship in a battle against Romulans.
Andie and the
Renown die together. It's quite moving when put to music as flashes of scenes.
