Nomad science fiction is different in that it emphasizes the idea of being rootless or having a constantly changing home. In traditional science fiction, there could be a strong sense of a home base, like the Federation in 'Star Trek'. But in nomad science fiction, the characters may not have such a stable place. They might be following resources, fleeing from something, or just exploring without a set destination. For example, in some post - apocalyptic nomad science fiction, people are nomads because the world has been destroyed and they have to keep moving to survive.
One classic in nomad science fiction is 'The Stars My Destination' by Alfred Bester. It features a character on a journey of self - discovery and revenge in a far - flung future, which has elements of the nomad concept as the protagonist is constantly on the move through different and often hostile environments.
In the fanfiction, the nomad might face various challenges and difficulties after getting hurt. Maybe they have to rely on the help of allies or find their own way to recover.
