Gradually the island fell silent. First, trade petered out and then ceased altogether. Onlookers muttered that with so much time spent on the wall, the builders simply had nothing left to sell. Next, the fishing boats stopped sailing from the ports, then the hearth smoke faded away and only a sandy haze was left hanging in the air; a death rattle of dust. Last of all to disappear were the sounds of building; the echo of brick on brick and the continual whine of pulleys.
Nobody can explain why the wall was started but there are many theories as to why it was never finished. Some say that so many had perished during its construction, that no one dared halt the work and thereby admit that it had all been in vain. Others claim that the builders simply ran out of materials and since they had scooped so much rock from the centre of the island, there was no land left to plough. There are those who believe that the bricks near the top of the wall are made from the baked bones of labourers who dropped from exhaustion further down. Or perhaps the islanders grew so used to the work that they just couldn't stop themselves. But one thing is certain, the prophesied threat never arrived and the people at the centre of the archipelago had, quite simply, bricked themselves in.
