The backers, or White Wolf?
Every previewed Purview came with an Innate power, a passive ongoing benefit for possessing the purview as well as two "Marvels" (or whatever the purview specific abilities are called).
Like, for example, the Water purview:
Innate power: Breathes Water as if air, ignores all Obstacles for moving or acting within water, immune to harm water temperature or pressure.
The marvels are
Changing Tides: Imbue a legend to control the flow of a body of water out to long range, rendering it placid and still even in a hurricane, or changing the currents as you see fit. You could reverse the flow of a river, or drag all the swimmers you can see to shore.
OR you can spend a legend to throw a massive forceful wave to crush your enemies, making an attack with (highest Power Attribute)+Occult with Enhancement 4. This attack has the shockwave tag, meaning it will hit all enemies in the same range band, as well as the Bashing and Pushing tags.
The other marvel is called Reborn from the Depths. You imbue a legend, and spend a scene submerged in water. At the end of the scene, heal a -2 injury, or a -4 if your -2s are clear. As a simple action while submerged, you may extend your senses to any point in the same body of water within long range, seeing and hearing as if you were standing at that location.
Will there be more than 3 abilities per purview in the release? Idk. I just know what they told me.
Note also that these previews aren't exactly new, so it's entirely possible some details have changed.
