Rewrite your favourite fairytale, so that it is set far, far in the future.
Consider the following aspects:
- weather and climate.
- environment – city or remote outpost, earth or some distant planet.
- technology, or a lack of technology.
- people (or aliens) – how they appear and act.
- culture and language changes.
- any world-shattering events that happened in between that could change your fairytale in significant ways.
