One Cannot Die|| A story told in instalments|| 3/6 done!

The cold marble chilled my paws. It turned my blood to ice. My large, oversized kit paws were beginning to grow numb. Fear was in the very air, surrounding me, choking me, making it hard to breathe. I could hear the guard's claws clicking on the tile as he padded behind me. The throne before me was a monstrosity. It was made of scales of what I now know to be a dragon. Feathers- from the wings of the griffons- adorned the top of the throne. The throne was red- a deep, dark red. I now know that is blood- prey blood, cat blood, dragon blood, griffon blood, unicorn blood and many others. I felt so small, so weak. My brother stood beside the throne, looking somewhat murderous. My sister was a few steps to the side of the throne, her face expressionless. I kept my head low as I passed the portrait- and as I passed my brother. I stood before the throne and turned to face the guards, the cleaners, the servants and the slaves. 
"All hail King Colchir!" The guard who had been following me in, Clayton, bellowed. 
"King Colchir!" came the reply. The tone was mixed; some were pleased, others angry, some racked with grief. I turned to face the throne and, swallowing my fear, I climbed onto it and sat down. The crowds began to leave. My brother padded over to me and bared his teeth.
"That should have been me." He whisked away, dark brown tabby pelt bushing. I wished I could call after him; beg him to listen. But instead I hung my head, shrinking away from myself and the world. My light orange paws on the dark, dark red throne were all I could see.
"Don't listen to Misclin," said a voice I recognised as my sister's. "He doesn't understand." I looked up and managed a weak smile.
"Thanks, Riniski," I meowed. She bowed and left me looking out over the chamber. My chamber, part of my kingdom. And I was completely miserable.
I had killed before, many times before, but this time was different. It was as if a part of my soul had died with her; no, a part of my soul did die with her, that fateful night. I had to do it. There was no choice. Longidi would have slaughtered me. This murder, though; this one, would make me what I am now. It was raining, on that night. My fur was plastered flat against my skin, the water drenching me, yet I felt no cold. I felt only remorse for what I was about to do. There was no choice. My reward was immortality; my punishment was death. I wished for neither, hungered for both. I didn't want her dead, yet I didn't want to die. I didn't want to be immortal, yet I didn't want mortality. I had forced my emotions from my body; severed them in a way only I could do. Then I did it. One simple cut. One simple claw. One bloody corpse. Yet the grief that racked my body was agonising; I had killed her. I felt strength like I had never felt before, power beyond description, as the immortality flew into me, consuming my soul. My grief faded away to nothing, my muscles hardened. I closed my eyes, relishing the feeling. When I finally opened my eyes and cast the skyward, I was changed. My amber eyes glowed in the night air. I was no longer a king; I no longer ruled where my pitiful, weak, feeble father had; no. I was a god, an immortal. My claws were as sharp as swords, my teeth like knives, my muscles like stone. I felt no remorse for the ones I killed; I had become a monster. I was no longer King Colchir, the one who had been crowned too young as a small kit, the one who had been scared of his own shadow, the one who had almost died of an asthma attack. I was Colchir, bane of the gods, slayer of enemies, assassin of the weak, the strongest immortal to exist, the one to kill her. Colchir, bane of the gods, slayer of Morgra. Yes, that sounded great. But my story had barely begun.

I needed to reconnect with my former self. My own sanity was at stake. I glanced at the she-cat- no, my sister, who was standing beside me. That simple connect almost made me collapse. It was if Longidi had stolen my identity. Every thought of my past self made my head hurt, my muscles contract and my legs shake.
"Think of Misclin," Riniski ordered. I shook my head.
"Misclin is dead," I meowed harshly.
"Dead?" Riniski's ears flattened. "Since when?"
"Last night," I replied, without fear. "It was another of my jobs."
"Your jobs?" The she-cat's fur fluffed up. "Longidi is making you kill?"
"Longidi does not make me do anything!" My claws unsheathed in anger. "It is simply my duty." I looked at her and an idea flashed into my mind. "Just as it shall be yours."
"What... what are you talking about, Colchir?" Riniski shrank away from me slightly as I approached her.
"Oh, nothing," I said, licking a claw. I quickly slashed open her chest. Riniski looked at me in shock.
"Why, brother?"
"I have done you no harm," I replied, then let out a maddened laugh. "Well, unless you count losing your very mind as harm..." Riniski's pupils dilated then shrunk. Wings sprouted from her back. Bony horns burst from her skull, making her cry out in pain. Her teeth grew longer and sharper; becoming like knives. Her cries quietened, then stopped. She turned to me, grinning.
"So, brother," she said, twitching her wing and ear simultaneously. She then bared her teeth. "Who is our first victim?" My smile widened as she unsheathed her claws and raked the ground. She was ready. The first of many, many of my demons.
