 ## Sensoria
 
-TODO
+The ways in which an instance interacts with the world are mediated through their *sensorium*. The sensorium is the sum total of all senses that an individual has. This includes the usual senses as well as those sensations particular to the System, such as interacting with the perisystem architecture or the feasibility of creation or forking, both of which will be described below.
+
+For instance, one may sense the current time and date, or sense the permissions of the sim in which they're currently residing.
+
+What these additional senses boil down to is *intent*. When moving from sim to sim, one moves with the intent to do so. Similarly, when one creates an item of clothing to wear, one leans on this sense of intent to bring it into being. ((Yared quote))
+
+These *sensoria* are flexible and open to modification. If one is overwhelmed by just how noisy a nightclub sim is, one can simply turn down their sense of hearing, just as, if one is trying to be particularly stealthy, one can turn their sense of hearing up in order to listen for potential dangers.
+
+One final use of sensoria is to send *sensorium messages*. These are senses that are shared between two or more individuals. If, say, one wanted to send one's friend a quick message, they could start a sensorium message, begin speaking, and their friend would hear those very same words as the sender hears them. These messages are not limited in what senses may be shared, though the messages themselves may focus on only one or two senses in particular.
+
+For instance, one might wish to share with a friend the feeling of the ACLs of a space changing without speaking out loud, or perhaps the full experience of a delicious meal.
