5. Promise
Kai, in spite of all his anger at the world, finds solace in his dreams as they put his tense body at ease and takes his mind far away from his dangerously dark and consuming thoughts of hatred and vengeance.
Just as he is never one to idle while the raw power of his animosity crawled annoyingly in the marrows of his bones, his dreams are just as harrowing and grim as his countenance. On some nights, he might just be lucky enough to dream of nothing but the back of his eyelids, but Kai counts those dreams as his worst ones. The darkness continues to suffocate him just like it had suffocated his Other, so he prefers his dreams to have life to them even if it means they consist mostly of splattered blood, dangling bits of gore, and the rot of death's fingers looming from above.
To Kai, his reality is the best dream because it keeps him grounded and sane. Without his anger, his last remaining tether to his own person, he would be just as dead as his Other. He would be doomed to a life wandering like a lost soul without a purpose, because without his Other he is only half of a soul.
Tired and exhausted, Kai stares into the twisting, dancing, crackling flames of the campfire and clenches his shaking hands into a white-knuckled grip around his bow before promising, silently, that he will have his revenge on the darkness that took away half of his soul and sanity in this life, or the next:
Twin.
