The first thing will be the characters. Five seems to be a standard number for team-based stories. Create a Bio for each one.
1: So we have a Captain. I imagined him as older with white hair. I'll keep that. He apologized, so I'll base his personality around that.
We have a polite Captain who must be in touch with his emotions enough to realize they might be slipping away and he may behave in a less caring fashion as time passed. Obviously a concern for him.
His background could be from a nice home on Earth.
I would say, not a military Captain. (Not that Military Captains can't be polite.)
Since there was at least one alien plant in the hydroponics lab, I'll pick Scientist as his profession.
I'll search on a name site. I'll type in Respect, switch to search meanings, and search. Erhard looks good to me, so I'll go with that one.
Sometimes different sites give entirely different meanings for names. So be careful if that matters to you.
I'll search Google for German surnames. I'll click on the first thing that shows up and I'll go with Schreiber as in a scribe.
2: We have a woman in the hydroponics bay. I'm imagining her as a brunette. Can't remember if she was in the dream. Maybe a little on the shorter side to contrast with the large flower.
Perhaps have her as a Botanist.
She wasn't screaming or running from the alien who was bigger than her, but she was afraid of it. Will remember this for when writing her character.
I'll search on a name site, 20000-names. I'll add External Link at bottom of chapter for this one.
I'll type in Botanist, scroll down to "Flower Names page 2," CTRL-F to find Botanist, and pick Dahl as the surname.
I'll go back, scroll down more, search through "Flower Names page 3" and pick Linn.
Because of the meaning of Linn, I will have her be a twin, and the other twin is not on the ship. It could lend itself to some emotional storytelling.
3: There were other crew members on the bridge for the Captain to be talking to. I'll go with three more on the bridge to bring the character total to five. I'll figure these out later if they're needed for tutorial.
