So a few questions;

- When is this set/when did the earthquake take place so that we know the technology level of the time.
- Just for flavour, how is the agriculture and land of the settlement?
- What other areas or groups of interest would there be in the local area or that people would know of?
- Where in the world is the settlement as well as the ethnicities? I wouldn't wish to create a Canadian and it is set in Japan, etc etc. (I'm assuming that it's somewhere in America?).
- What rules would there be? Is gun-carrying permitted? Are guns permitted?
- Did religions survive the 'quakes or have new ones sprouted?
- What would be the average education level of the typical adult of the camp, also is there a general education or are people raised to carry out a specific job for the future, for example an engineer school or a military academy.
