Brilliant, Amirani! Ren's calm shattered by the reveal of first his face and then the others on the corpse forces him to take stock. The beauty that I see in your story is the multitude of meanings from the message sent by the river. One, that his anger and rage are the enemies, which will claim not only him but his foe, loved ones and unknown others if he continues to carry them in his heart. Or, that death is the ultimate enemy, one that defeats us all in the end. Best to let the negatives in life fall away and to embrace with joy those who matter the most to you while you're still alive.
