# Revelation Space (series)
## Overview
- Work_type:: hard-SF space opera
- Setting:: Far-future galaxy with human and post-human factions
- Scale:: Fully interstellar, with multi-system civilizations and millennia-long histories
## Trans-human form
- Transhuman_type:: hybrid
- Mechanism:: Extensive biological and cybernetic augmentation; long-term shipboard life; some partial digitization
- Degree_of_change:: High; many characters are physically and cognitively far beyond baseline
## Survival logic
- Survival_strategy:: Engineer humans into “ultras” who can withstand deep-space travel, long lifespans, and harsh environments
- Key_technologies:: Advanced medical nanotech, cybernetic interfaces, relativistic starships
- Main_constraints_addressed:: Time delays, radiation, resource scarcity, and fragile bodies
## View on baseline humanity
- View_on_baseline:: replacement
- Attitude:: Baseline humans persist but are marginalized; enduring power lies with heavily modified or machine-linked groups
- Identity_question:: Raises questions about whether ultras and other variants still count as human in culture and values
## Notes
- Themes:: Degenerate civilizations, cosmic-scale threats, costs of deep alteration
- Open_questions:: Whether long-term survival demands sacrificing baseline human norms
