  Power words are ancient pieces of the sorcerous truespeak from the dawn times of the world. They are inherently unknowable, and creatures who hear one spoken irresistably forget the exact structure of its syllables immediately after hearing it. They can not be recorded, transcribed or preverved by any mortal magic; however, certain powerful divinations can grant a skilled mage knowledge of a Power Word just long enough to speak it once, allowing its terrible effect to take hold on the world.
   One of the earliest and simplest power words, 'Stop' freezes a single target creature in place, preventing it from walking, running, jumping or otherwise moving naturally. The effect does not prevent teleportation, nor does it stop the creature from being knocked prone or bull rushed. The creature is not paralyzed, simply fixed in place, and can still make melee and ranged attacks. Free action negates this power word, but like all power words there is no saving throw against its effects.
