I believe the answer is:
page
I believe this is a double definition.
'summon' is the first definition.

(Other definitions for page that I've seen before include "Errand boy at hotel, club etc" , "Leaf; call over PA system" , "Sheet of book" , "Boy at match" , "Young attendant for part of a book" .)
