“ A nation state has a hardline tradition of transparency in government. So much so that any and all information held by their military and intelligence services is immediately declassified and published when the said information is no longer relevent to current and ongoing activities. Even if such information might be diplomatically toxic.”
“ Believable magic, like ordinary physicis, operates according to some invariable laws that always result in some kind of cost or 'bounce back'. The grater the magic, the more it should cost the character physically, emotionally, and spiritually.”
“ A powerful wizard that the PCs encounter is completely silent. He does not speak and cannot be heard as he moves. Even his spells are silent, but his magic is just as potent.
He has a tendency to summon invisible chairs, place foes in invisible boxes of force, and other 'mime tricks'.”
