How to develop supernatural power?

The World of Darkness resembles the contemporary world, but darker, more devious, more conspiratorial. Humanity is losing hope as it is preyed upon by supernatural creatures such as vampires, werewolves and wraiths. One facet that sets the World of Darkness apart from most other horror fiction is that these creatures are not solitary predators to be hunted down and destroyed, but they are numerous and intelligent; enough so to form societies, develop various factions and allegiances, and use humans as pawns in their power struggles and murderous games. However, the rising tide of human civilization is too much for many of them to bear, and an atmosphere of hopelessness presides over many of the games as once-mighty supernatural beings, the dark Princes and Lords of a previous era, now face the bleak and unbearable prospect of a future spent straining and shrinking under the ever-and-ever more meticulous systematization and control of a power-obsessed mankind.While at the same time humanity flounders under this hidden oppresion, prey and pawns to enemies they cannot fight or are even aware of.
