It is late summer in the first year of the fortress called Registbar, or Gloverose. The seven were sent out to settle a riverside area to establish a primarily agricultural fort away from the rest of the Dwarven civilization. Hopefully, it will provide an eventual respite against the constant wars with the nearby Goblin civilization, a place to retreat to. Hiding in the mountains is no longer enough.
Unfortunately, the dwarves have been ordered to build their fort completely above-ground by their leader: Avuz the goblin, Queen of the Infallible Paints. Even if they wanted to, the soft sand, so different from the familiar stone of their mountain homes, is impossible to dig into without risking catastrophic collapses due to instability. Without any other choice, the seven strike the trees. The result is meager and depressing. With trees running out and food supplies inconsistent, the new migrant wave poses a significant problem. The reinforcements, each of them combat dwarves, bring new orders from the queen: settle, build, and grow into a new capital city fit for the refugees of the mountains. The goblins will never suspect a wooden fort in a forest. They will be safe.
It is quite the paradigm shift for the dwarves led by the goblin queen. While they munch on their strangely sweet outdoor berries in the rain, the beginning of complaints can be heard during idle conversation. They miss the mountains. They miss their home. Only two seasons in, the weight of their situation is only beginning to sink in.
And the goblins already know.
