All sentient races are known to create three things in common which have been detailed to represent the classification of a civilization:
1. Language
2. Mathematics
3. Violence
From the beginnings of space travel, the Arkasti Space Exploration Rocketry Administration (SERA) had to tackle the issue of astronauts getting 'punchy' with one another in close quarters for long trips. This became increasingly difficult with the launch of SERA's first interstellar ship which carried a crew of 12 to another planet.
SERA performed numerous psychiatric evaluations, enlisted numerous doctors to train the crew in anger management, and equipped the ship with several tools to regulate the crew's overall social health.
However, even SERA could not forsee the mysterious murder of the ship's captain. The power vacuum cause a fight to break out between first officer Zeida and equally ranked lady Rufina of the Kaida royal family. The fight required several crew members to break up and both officers were confined to quarters for 25 hours until the crew decided on a simple-majority vote to elect the next captain.
This is a very nice mash-up of characters about to kill each other. I especially like the deadpan chick about to fire a gun over their heads.
