Since Declarations got brought up, and I didn't want to make a new thread...
If I have NPC "crazed Cultists" practicing their crazy zany rituals, and doing magic via some entity, can I make declarations as the GM? I know I can just say, it happens, cause it's off screen, but in case something is happening on screen or I don't particularly care whether they succeed or not, I just want to see how the dice fall, do I have the declaration option or is that purely the realm of the PC's?
