It is the fifth month in the year 1101 Anno Domini. After the slaughter in Jerusalem You left with a few good men to explore the vast Syrian expanses east of the Holy City. You have had some minor skirmishes during the last few months, but the area You are in now seems quiet.
This morning, when following a dry riverbed, Your scouts found an old castle - a few defenders fled when sighting Your patrol - and You are now inspecting the walls and towers. The castle seems to be ancient, probably Byzantine in origin, with a few more recent additions. You understand why the defenders fled: The overall condition of the castle is by no means satisfactory.
You see possibilities, even though the local bedou tell You that no trading caravan have passed through this area for years. By building a new strong castle, You can control the surroundings and take advantage of its resources.
The bedou call the place "Wadi l-Kbir", which should mean something like "The big riverbed". The bedou have their camp near the castle, and - although followers of the Prophet Muhamed - they do not appear to be hostile towards You. They seem very willing to sell their services for gold, but You doubt if You can rely on them in the long run. Attracting more crusaders to the castle should be a priority.
You have set the goals for Yourself:
1) Rebuild the castle.
2) Attract 42 sturdy men and women.
3) Brew enough ale for all to have their promised daily ration of 12 pints.
4) Stock enough to arm and equip at least 30 knights (30 swords and armour).
5) Show everyone Your dominion of Wadi l-Kbir, and that You can face any hardship, at least for two full years.
