What you feel and interpret as longing is in fact the sudden movement of your assemblage point.
Ruthlessness makes sorcerers' eyes shine, and that shine beckons intent. Each spot to which their assemblage points move is indicated by a specific shine of their eyes. Since their eyes have their own memory, they can call up the recollection of any spot by calling up the specific shine associated with that spot.
The reason sorcerers put so much emphasis on the shine of their eyes and on their gaze is because the eyes are directly connected to intent. Contradictory as it might sound, the truth is that the eyes are only superficially connected to the world of everyday life. Their deeper connection is to the abstract.
Man's possibilities are so vast and mysterious that sorcerers, rather than thinking about them, have chosen to explore them, with no hope of ever understanding them.

The only advantages sorcerers may have over average men is that they have stored their energy, which means a more precise, clearer connecting link with intent. Naturally, it also means they can recollect at will, using the shine of their eyes to move their assemblage points.
