"My Tertsman!" a voice called, I turned around to see my Infsman, Terratora running towards me. "Terra?" I asked, "what are you doing here?" "I was suppose to inform you about the recently finished tasks, but it seems you have found... their door. You musn't go in there my Tertsman. " Terratora caught my attention on her emphasis on the word 'their' "What do you mean 'their?'" I asked "Behind this door..." she paused for a long second, as if she hesitated to answer, "lies four unannounced Neuronites, if they are even considered one" This left me pondering and confused, "Four more Neuronites... how? There are already four members in our squad, how could there be four more?" Terratora didn't answer, but rather, she looked down stayed silent I continued to ask here more questions "And more importantly, when and how was there a door here?" She sighed, "I think it's time... that I told to you about the Shadow Squad." This story takes place in a girl's human mind, which is more known in this universe as the Psyche Realm. It tells about the Infsman(inferior function), Terratora of the INFP Squad and her encounter of the four additional CFs who mysteriously appeared in their Realm.
