Post Apocalyptic Survivalist -
Where were you when the Big Bang hit? We get by as well as we can since we rediscovered steam powered generators. We've never known anything else. Our ancestor's over reliance on machines and computers forced us to learn how to do everything by hand again, from growing our own food, to making our own clothes. Fabric is hard to come by, and our clothes are made from anything we can get our hands on. Everything is practical. Everything has a purpose. Nothing gets wasted.
Winters aren’t as cold, and Summers aren’t as hot as they used to be since the Big Bang screwed with our weather patterns. We may not have gone to school, but we can strip and reassemble engine in less than a few hours. The Post Apocalyptic Survivalist is an example of a multi-intergrational genre element one can add to their Steampunk personality, akin to the Time Traveller.
