Droma

Following a worldwide cataclysm, the isolated and remote island of Droma has had no contact with other peoples except a little desultory trade with the country of Valkil ('it's a very long way away to the south and west). The people have lived a hard life, but completely without conflict for generations and have acknowledged no enemy except the weather. One day in summer an army from Valkil invades, intent upon conquest. No-one has ever heard of a peaceful society putting one over on an invading army before, but that's only because it had't been done right before, not that it couldn't be. Just a few individuals at first, but ultimately every single Droman, will have no truck with ideas as ridiculous as fighting and war and set about resisting. But not with weapons.They don't have any to begin with, they don't even have a word for them. There are other ways, ways that the Dromans have never thought of, let alone the Valkiets.
