Firstly, I have a question for the GM: in case of a replacement, do the clues go to the profile of the “new” player, or the “old” one? If the latter, then how are the questions resolved?
Next:
The Search for the Grail. In the 9th century, Europe began to “hunt” for relics associated with the earthly life of Christ. This process reached its peak in the 13th century, when Louis IX brought to Paris...
With this logic, you can come up with connections to many things. Should I demonstrate?
A clue always has two characteristics: 1) the chain is clear, unambiguous, and leads to only one person, 2) it must have feedback. That is, the GM, looking at the player’s profile/quest log, can ultimately come to the conclusion that is indicated in the clue.
