Apples

The bitter fruits on the "Trees of Death", as the people called them, were poisonous. They found this out on their first expedition, to find a new place to live and the little colony did find a place. A place at the price of Twenty men's lives, before they figured out that all the trees in the forest bore deathly poisonous fruit. They also realized that all the fruit they planted was also tainted. The poor villagers would never be able to live here, in the tainted utopia. All would be lost, and they would never be seen ever again.
