[For the following, I believe that experiencing it from the receiving end would be more telling than Isaac's twisted representation, another reason is that his thoughts during this seem a little deranged.
"As beautiful as this darkness is, isn't it more a hindrance than an advantage? I feel like I'm melting in this bubble" said the Vice-Archon, his voice was grand and strong, his sister, another Vice-Archon, spoke "The Seer that produced it gave his life to do so, it's all in God's plan-" "Of course, sister, but he did not know what this bubble would do, what if it does not fall?" their argument became stronger and stronger, in the presence of greater beings like them, we are surely unstoppable. One of the Seers stopped. "Wait..." he commanded, "Something's wrong..." he continued, the male Vice-Archon stepped forward to him, "What is it now, old man?" his sister held up her hand to her brother, "tell us what you see, great Seer." She is so kind and diplomatic. How fortunate are we that such a great being is with us? His movements became stiff, and another being spoke through him, he took a deep breath, "Listen and listen well. Five will become three, the two, one. Heed my warning, Die Well." The Seer's head inflated, blood pooling out of his mouth, his head then exploded. "Why do Seers always end up killing themselves?" The male Vice-Archon asked sarcastically, his sister did not listen, but knelt and prayed to the glorious God, "Oh, mighty one, slayer of false, take your son into your arms and add him to your undying legions..." The four Seers joined in "...And may your son serve you forevermore" The brother rolled his eyes, "he's going to join them anyways, why pray for something certain?" his sister opened her mouth to answer but thought against it and only sighed. "We must heed the warning," said another Seer "A Seer's death is certain, as is the death of one of the Vice-" The brother grabbed the Seer by the throat, "No. Keep speaking and your death will be certain." another of the Seer's was lifted into the air, kicking and screaming, "Sister, I'll handle-" he was cut short, the sister had disappeared. "Sister?" her limp corpse dropped from above, staining the stone floor with fresh blood, her ribs had been opened, her lungs on display... "Oh, no, it's him, it's the Butcher..." said one of my initiate brothers, A loud snap sounded and the Seer went limp in the air. Everyone stopped, no one moved or breathed."Sister...?" his voice was quiet and low, "SISTER!!" his voice roared, his body morphing into his true form, it was akin to an insect with skin, four-pointed legs, digging into the floor, two long three-fingered grabbing hands, large pincers, reddened eyes. "I'll KILL YOU, BASTAR-" a man fell from the roof, a sword splitting the head and neck of the brother, killing him instantly, before anyone could react, a wide arc of electricity erupted from his hand, all but four initiates, including me, died, all of the Seers fell. One of us tried to run, but three daggers found themselves thrown into his back and neck. I froze, the two survivors ran and hid, but my legs wouldn't listen, I couldn't move. A fist knocked me off of my feet and threw me to the ground in front of the hiding brothers. The Behemoth had struck me and charged at the man, he revealed a war hammer from his spatial dimension, the torches we had carried had fallen to the ground and illuminated him and the grand creation, he swung as it charged past him. Hitting the back of its leg, making it topple. He swung again at the head then at the body until it stopped moving and screaming. Out of the twenty-six of us that came, only three of us got out alive to tell the tale. So now I lie in bed, about to tell the tale to the Archon. If I don't make it, tell my daughter that I was wrong. Our God isn't mighty, he isn't True, and that monster was proof of that. That butcher has a stronger and truer God than I. Amelia, If I don't survive, I'm sorry. My little Rose... It's my fault. I should never have joined them. I should've refused and died with your mother. I love you, My Rose.I apologise for adding another one of these madmen here, but it was necessary for you to fully grasp the horror Isaac can produce. If you are curious about the writer of this, I am afraid he never saw his daughter again.]
