This spell is a part of the Influence spell chain and is found in the Influence rune stone.
The mind already knows more than it realizes. This is something Dream has always understood. Knowledge of a thing, any knowledge, creates a connection between the knower and the known that the mind can follow if it is willing to reach. Scry is the mentimancer learning to reach.
With knowledge of what they seek - its appearance, its nature, something unique and specific that belongs to it - the mentimancer reaches through Dream and lets that knowledge become a thread. Dream follows it. The realization arrives not as a vision, not as a message, but as a sudden flooding certainty concerning the direction, the distance, the sense of where. Cast over a map and the connection becomes visible, a small glowing point settling over the location where what was sought can be found.
The limitation is the knowledge itself. Dream cannot find what the mind has never encountered. It can only follow threads that already exist. But anything known, truly known, leaves a mark in the mind that Dream can trace to its source. The mentimancer simply has to be willing to look.
