Victory on Janus

The planet Janus was covered in tall jungles and those that were trying to remake the planet in their image found that they needed labourers to help make the world theirs. Unfortunately, there was little to attract those who had other options, so they had to resort to indentured labourers, slaves in all but name. Nor were the labourers treated well. Worked hard when well and abandoned when ill. But Janus had secrets from long dead civilisations and mankind should tred carefully on its new homeworld.
