Four visible corners should be enough. Yet in the marginal maps there is another turn, beyond the court’s limits, labelled the Fourth Corner. Its name does nothing to solve the geometry.
Some fragments offer it as a refuge for what a reading cannot contain. Three cards have been considered closely, and something in the question still has no place among them. The corner lets that remainder exist without forcing it into a finished account.
Other marginalia follow a reader farther out. Each uncertainty becomes an invitation to add a detail. Soon the account is complete, but its most convincing parts have come from the reader. What felt like discovery happened beyond the reach of the spread.
The Moon and the Hanged Man belong near this impossible fold. A changed view may make room for what was overlooked; it may also conceal how much has been invented. The Fourth Asking belongs to this fold; it does not add a concealed position or a compulsory fourth card.
Archivists note that the Fourth Corner appears on more maps than the Shared Court. Impossible places, they suggest, are easier to draw than relational ones.
The map ends. The question need not be finished.
