Krokus Joe was a time miner. There were only a few time miners on Earth primarily because their average lifespan was so short. You see a time miner, once qualified, could earn huge sums of money but the dangers of time mining were significant. No one really knew why for sure, but often time miners would simply disappear and never be heard of again.
President Professor Ulnada EraDay, the World’s leading authority on time in the 23rd Century, has been quoted as saying that she believed that there was an organisation of beings ultimately controlling time and they periodically would act against any time miner who risked the universe’s delicate time-balance by mining too deeply.
Anyway, Krokus Joe was now in his forties which made him unique within the profession.
An Antipodean, Krokus put his success down to a micro-mining approach that he had invented, and kept carefully secret, plus a combination of “beer, fags and incinerated meat”.
