The Crowfall site has been updated with a lengthy post about the Knight archetype, his powers and with a brief look at the in-game UI.

iFrame Powers
This is a term you probably aren’t familiar with, so let’s define it. iFrame powers, on activation, typically remove the player from the physics simulation and render them invulnerable to damage while performing the power (a very short duration, obviously).
