An Apex is the figure that is responsible for the most fears that manifest in the Primordial Dream within a given area.
Every supernatural creature (and sometimes even mortals) have the potential to become the Apex. The requirement of becoming the Apex is regular contact with humanity, so a Vampire Elder that secludes themselves in their Haven has a low chance of becoming the Apex, while an actively meddling Changeling Court has a much higher chance.
In most cases, Beasts look to the Apex of a city as the leader, even if it is not a Begotten. Some Begotten, who have become the Apex, exploit this by sending nightmares to other Broods, bringing them to heel and forcing them to pay tribute.
