The Protoss have eternal lifespans and enough combat ability to explore the universe alone...
These are abilities many civilizations dream of, but the Protoss don’t think they’re anything special. Even the Protoss Council, one of the nineteen governing bodies in the Milky Way, doesn’t think they’re anything special...
The more indifferent they are to material needs, the more lost they feel; the easier it is to prolong life, the more lethargic they become. The troubles of an immortal species are so childish, so simple...
To put it simply: the laid-back heroine’s career of getting dragged into trouble.
The side story has nothing to do with the main story.
Also: I’m obsessed with worldbuilding and a committed hard science fiction fan.
