The current rules allow Pawns to move infinitely, picking up every noun in the process. The movement rule makes Pawns move by increasing the absolute value of their sanity (I believe this was an error in the proposal that made this change), and it doesn’t prevent Pawns from spending “negative” sanity (or the opposite depending on their nativity).

In “Pieces”, replace “A Pawn may move a piece assigned to them by decreasing their sanity by one if they are Native or increasing their sanity by one if they are Not Native.” with:

A Pawn may move a piece assigned to them by increasing their sanity by one if they are Native and have negative sanity, or decreasing their sanity by one if they are Not Native and have positive sanity.

Also, to prevent recharging your sanity every time you move, we need to change the spotting rule:

In “Spotting”, replace “Each time after completing this action a Pawn chooses to gain or lose 5 Sanity or 10 Sanity if they did the optional writing.” with:

After completing this action, and if they have not already done so that day, a Pawn may choose to gain or lose 5 Sanity (or 10 Sanity if they did the optional writing).

Remove any nouns that were picked up since this CfJ was posted from the inventories they were placed in.
Reset all sanity levels to the values they had when this CfJ was posted.
