From the Introduction: An outpost on Watchman Island (in Troskenia) will soon be swallowed up by the growing Etunakaimas, the world of the ettins, and be lost to man unless someone is able to halt the ettin power. The outpost has run out of men able and brave enough to venture into Etunakaimas in search for what causes it to grow, so they have sent arrows to the nearby settlements with request for aid, and the heads of the families of the player characters have decided that this is a good opportunity for them to prove themselves as real men.
