Does anybody here has an idea from what fan expansion this is? @wolnic ?
As players complete features on the board, their followers are held in a fortress (scoring an increasing number of points) but must wait until they are replaced by the next to complete a feature; apart from the last who remains until the end of the game!
If black completes this city, he gets 8 points for it, (3 city pieces + 1 shield)*2. The freed knight is placed in the Montsegur fortress on the first scoring space. Black receives an additional 2 points for this. The black knight must remain in the fortress until he or another player places a new knight in the fortress.If, for example, the road is finished by red, red gets 2 points for his road. The red serf is placed on the next valuation square (red gets another 4 points for this) and the black knight goes back to its owner.The monastery is also occupied differently: If the meadow adjacent to the monastery is placed another meadow tile (in this case with a city part), one cannot place a farmer on it, but a monk may be placed in the monastery.Red gets 9 points for completing the monastery, must place his knight on the next valuation space in the fortress and receives (in this example) an additional 10 points.The serf, who enters the fortress on the last valuation square (14 points), remains there until the game ends. So it is decisive when a road, city or monastery is finished. The longer a player waits, the more points he gets for his knight in the fortress, with, however, the risk that he will reach the last square and not get his serf back.
I've gone back to the document I created for all the Lost Expansions (originally this was for expansions mentioned on carcassonne.nl, an early Carcassonne fan site), and the notes for The Holy Grail lead me to be (almost) 100% sure that this is the start block from that expansion. Sample images, for the descriptions below, were missing in the original source.
I have written the name of the expansion to the person and now the corresponding rules have been found. Here is the picture
