Mission 1: The King's Beacon

Objectives: Build Beacon and Acquire 30 apples
Starting Goods: 20 Wood, 10 stone, zero gold

Place the granary near the wooden gate. Place two apple farms next to the granary and three saw mills in the nearby forest. When the first wood is delivered, place another apple farm and two more saw mills, thus employing all your peasants. The monks will automatically start working on the beacon when wood is available.

The beacon and the 30 apples should be completed in a few months. When complete, ships will sail by and avoid the rocks.
