A face stand is an Obesk device used to restore the larval face of the user on demand.
It is not used ingame nor is its function demonstrated, but it can be presumed that the device works like a mirror, offering the user a sculpture of their larval face that they may inspect and manipulate to sate feelings of 'flesh nostalgia'.
Its mere existence, as well as its occurrence in both Akizet and Kazki's rooms, suggest that 'flesh nostalgia' is a common feeling among Qou Obesk.
