A short door riddle

It is difficult to read, even with the torch since these scrawlings look very old, and are very old but the blood red soaked creature helps you when in need. You start to read with the creatures help,
" A while ago, humans in a village went out to fish, take food home to the family, in huts tribal huts, not africa or blacks, but very old humans. One time when fishing a glow hummed under the water, one looked then vanished, others fled in terror. Confused, scared, frightened, worried. Light from the water hummed louder, rising up near them, boats we're too weak. Could not escape, light physical, I touched I vanished, I looked up, I saw two creatures, I tried to defend myself, failed, creatures told me not to fear them, I had not choice, I obeyed. They..turned me, I had memories faint, but still their. Confused I tried talking. Fail, no lungs, But I not needed air, still confused, I try, again, again, again. Fail each time, I give up, I look around, vision is different. Vision like book said about cat, Night sight, able to see in darkest of places as if it were bright inside. I look around, two creatures stood, I try talking, failed, My head hurted, I heard voices in head, not mine, Not Mine! Theirs, I could talk In mind, not out loud, I look around again, Ignoring what the two saying, I see water, I go closer, It is top of a water falling, I finally listened to what they say, ( You have been brought to protect something, do you understand?) I turn and speak *Yes, who are you?* They speak, ( We are beings who created this plane, and you are our subjects) Person of white then holds object, It has hole near hand place, its long but small. They speak, ( If anyone holds this do not fight them, protect them, or bow) I ask, * What is object?* They resond a Key.. I am unsure what Key is, But I obey, I turn and look at water falling. They speak, ( Thats a waterfall, Do you like those?) I nod, and for first time I look at my body, It looked twisted, My flesh dark blood, My hands, leapord like, I felt holes on my neck, breathing ways like fish, I was disturbed by my body. I asked what they did, They respond, ( What we wanted, your a protecter, and you need help) Out of air, he brought many more from my village. I had not good feeling, he and the other turned them into like me, I could not speak to them, they were attacking the two figures, they failed. They passed, they could not come back, the two brought more, this time they obeyed, but I still could not speak to them. The two spoke, ( If you are trying to communicate to these creatures it wont work, only you have your memory. These do not) I was hurt, feeling of anger, regret. But could not do anything but watch, sad, I was sad. Many times had passed, I was still up in sky with two, then I was brought down, near water falling, or waterfall they said, ( This is where you will be now, protect the cave) I had pain feeling in head, when I opened my eyes, I say glow outline from a cave area. I then noticed I had more than one eye, I had six, I was scared, I looked around and noticed others, I tried talking but failed. I tried touching and something changed, they acted..different, almost normal like me, I put my hand? On one of them, their eyes turned from dark black red to lighter, I could talk to them now, they spoke (W-whats going on? where am I? Who-w-what are you?) I stopped them, I spoke * Not fear, You safe with us, we protect cave, two leaders said so* She looked confused, but it was hard to tell, She turned to cave then, her head hurt to it looked like. Then she saw too, she confused but understandable, we waited, time passed again, two creatures came down, they spoke, ( We have found a leader of this plane, he is a human from Earth, a male, If he comes here attack him on sight. Don't chase him if he runs) I agree, She agree, others confused do not respond, two figures act scary, creatures then agree, Her had question for two, * Who are you guys?* The two resond, ( None of your concern, we are just leaders here) She still confused, but slightly understanding situation, my mind is slowly falling, I can recognize good and bad, but humanity falling, main goal still applied, save key person, kill others, I fall to night, I awake fighting my head, It tried to take me over during night. have to be more carful. Two more nights passed, It becomming more agressive..and violent. 3 nights passed, I awoke in a completly different room, I understood that it finally took over at night, I looked down, I killed human, I was terrifed with what I done, But then I could not move, my eyes shut out, I could only watch, More people came, I hurt more, Killed more, decimated more.. I wanted to stop but had no power..after many time passed two creatures came down again, they spoke, ( We have found the perfect candidant, please try your best to stop him, if you do you may have your freedom. But remember If he has they key, Do Not Engage, Goodbye creatures) They vanished, havent returned yet, I wait scared, Dont want to hurt, Dont want to kill, want to hide or escape, cant, I write this with my still concious memories, I dont know if I will lose them, but I hope not, If I find you, person with key and I bring you here, It is to say, I still have memories, and I want you to know what happened here, and how this place was created and why you were brought here. That is all, good luck human!"
That's the end of the scrawling...
