The two guys were progressing through the dark castle, noticing that everything was dead. The place was covered in the skeletons of the dead, indicating they were dead for a long time, as well as the cobwebs that covered their bones. Though, the one sign of life in the castle were the torches lit in a path, directing the two where to go as they aimlessly followed.
After walking forward, through several corridors and other large rooms, the two men would arrive in the same room at the same time, each of them at the opposite side of the room. Their childish squables from before had subsided, and the two were elated to see eachother. They moved to greet eachother now, quickly moving across the room.
Unfortunately once they arrived to the center of the room the doors quickly slammed behind them, and the girlish laughter of the voice that led them here would be clearly audible. No longer just in their heads, it was with them, in the darkness. It was then they realized that both were being tricked by the voice, being led to this trap by it.
The laughter ended as torches would light up the entire room for the two to see, as they realized they were in some type of torture room. It was covered in tools and devices of torture, all covered in dried blood from their last use. In a cage hanging from the ceiling, there was even still a skeleton. The two looked in horror, unsure of what they could do, until they heard the screeching, now twisted and malevolent voice in their minds once more.
"Here's the game my toys... I need the blood of the stronger between you... And it needs to be fresh blood coming from a living one... If you want to leave this forest, as I promised you, I'll just ask you one last thing in exchange for my assistance... I want you to tear off every. Little. Part. Of your friend's body. If you refuse, I will have to take care of you myself with the machines in this room. Please observe, that you can put your friend out in a mercy killing now, instead of both suffering.
It was perhaps the worst possible situation, two best of friends now forced to fight to live, neither wanting to die and putting their own lives over the other. At first what was a fist fight became a full on blood battle as the torture tools began to be used as weapons. One was stabbed in the shoulder, and lost their arm.
By the end of it, after ten minutes of gory battle, the two boys were left mortally wounded. One had lost an arm and his guts were hanging out of his stomach. Meanwhile the other had both his knees crushed in, been blinded, and was heavily bleeding. Neither were going to make it as they were bleeding out. 
Slowly dying on the ground as their last breaths were resonating in the room, the girl finally made an appearance, giggling next to them as she leaned towards the one who could see her. She then pushed her heel slowly inside his skull, arching her back to grab his chin as she was roughly pulling it in her direction, his neck about to be torn from his chest while he was crying blood and tears. The other man was listening at this horrible scene, unable to do anything besides beg the woman to stop until he heared the terrible sound of his friend's head being ripped off.
His face was pitiful, covered in blood and tears as he layed there wishing to die, having that wish slowly granted. "Why, why us? We were innocent? You promised you would help us out of here..."
The girl laughed as she leaned in to hear his crying, whispering in reply. "What are you talking about my dear~? You did your job very well, you awakened me. And now I will set your soul free from the bindings of your body." After these words, the girl raised her heavy scythe, and in one fast movement of her arms, she sliced his body down the middle, in two parts as the rough sound of his bones crushing and being sliced, and the skin being pulled apart were heard.
