[ a missive not meant to last, then. kaveh gets to work; alhaitham finishes his. he does not look up until kaveh approaches once more. with the imperative tones of nobility, looking down on his nose. alhaitham, who is amused, considers the way kaveh looks. he then reaches for a sheathe of feathers that sit on his desk. blue, green, in the way of fanned peacocks and the imperious crown of lyrebirds - he takes one feather from the stack, and hands it to kaveh.

a shoulderless shrug: ]

There is no need to bother me every time you wish to send for her. There is a pneumatic tube by the door. Put the feather through. It will reach her, and she will be here.

[ the permission is implicit - do as you like. alhaitham's authority in this is conferred to kaveh. ]
