A report by Velham Jedley. The Hephaestan Oxygen Company, a semi-autonomous body charged with maintaining Hephaestus' shakey oxygen supply, has revealed plans to implant all residents with 'aerometers', which register the amount of oxygen consumed by an individual, who would then be charged accordingly. Visitors to the planet would be obliged to pay a 'consumption charge'. Pressure groups were up in arms at the news yesterday, but H.O.C. chairman Diveset Opes shrugged and said 'It's the only way to go'.
