The Chess

Walking through the door. Four masculine men and a strong woman. They looked young, all in their twenties, but powerful. They walked in as if they own the place.
"Don't you know who these are?" a man was asking his questioning wife, when she shook her head, he said "these are the chess".
"The what?" she asked
" The chess, the king" he said pointing at the man in the middle front.
"The best friend, most trusted and the one who runs all his and the palace's affairs" pointing at the woman.
" The prince cousin and the head of the air force" pointing at the man on his left.
" The other friend and the head of the intelligence system" pointing at the other man on the left.
" and him?" she asked refering to the last man.
" I don't know and no one knows but he is new and became one of them but no one knows anything about him, yet" he said
" They run our world"...
