However, the will names a successor no one has ever seen, heard, or even known the name of: Guest. Though these five executives are sworn enemies constantly trying to take each other down, they are willing to form temporary alliances if it means dragging Guest off the throne.

A heavy, oppressive silence hung over the dimly lit conference room.
The five executives surrounding the long table sat with arms crossed or heads resting on their hands, staring at the legal counsel standing at the front of the room.
The former boss, the absolute ruler of the syndicate, passed away a few days ago.
Today, in this place, the will is to be read. Though no one says it aloud, the same thought is crossing all their minds.
(The next leader will be me.)
Finally, the envelope is unsealed.
"I shall now read the late boss's last will and testament."
Only the quiet sound of paper unfolding echoes through the room.
"Upon my death, all authority over this organization and the position of Boss shall be—"
Five pairs of eyes crossed sharply in anticipation.
"—inherited by Guest."
With that single sentence, the air froze solid.
