For those of you who are wondering about the poison: it's really the whole secret of the story, so I can't exactly tell you anything about it. All I give you is a clue. If you would like to know it, PM us, we will send it to you.
We hope some questions will be answered in this songfic.

On the Brink

Pohatu sped through the sand dunes in Po-Wahi. Seven years ago, Toa Tahu Nuva of Fire had been the first to catch it, the poison. Two years after him was Toa Onua Nuva of Earth. It had been only last month that Toa Kopaka Nuva of Ice had committed suicide.
This poison, something so deadly as it had wiped out civilizations long ago, had reached Mata Nui and was beginning to, not only kill the Toa Nuva, but the Matoran as well. But it was only in resent week. Hewkii was the first Matoran. Soon five others had followed. Now it was his turn. His, the Toa of Stone's.

Well I'm on the brink, of something horrible
Just what it is I'm not to sure
But I can't take it anymore (round 1 fight)

The Toa of Stone arrived at the place he had been heading, the place he had first landed on the tropical paradise. He breathed in the salty air. Pohatu had never been the biggest fan of water, but the ocean, it was different, somehow. The saline air comforted him, it eased his tensed soul for the past few days.
I have only had this poison for the past day or so. I'm so edgy even Lewa noticed. I need to relax.
He sat on a boulder crossed legged, never moving from the position. His copper gaze watched the silver waves draw in and out. He watched as the silver became gold. He watched as the tide came in. He watched as the moon rose, leaving the gold to become dark blue and to reflect the moon and stars that shone above.

I can't explain the feeling that I feel,
I'm not even sure that they're for real
Doesn't work to end in sour tales

Toa Pohatu Nuva sat on the boulder throughout the night. He had never been one to meditate, but now, it seemed vital.
"Stonebrother?" a soft voice asked from behind him.
"Yes, Lewa?" Pohatu asked without turning around.
" I have been trying to wayfind you." Lewa said, helping his brother off the boulder.
"You have?"
"Yes, Watersister has called a meetinggather in Toaclearing."
"Thank you, Brother Lewa."
"Always gladhappy to help!" And, with that, Lewa soared into the clear blue skies.

Go to sleep so I can wake up
Wondering why things are this way
What the fuck did I say?
To make you hate me any way

"Sister Gali, where is Brother Takanuva?" Pohatu asked when he arrived to the clearing in Le-Wahi. When he had arrived, Gali had been pacing back and forth nervously. Lewa was sitting in a branch, the highest one from the ground, yet close enough so he could hear conversations. The Toa Nuva of Stone had almost not seen him, for his leaf green coloring was amazing camouflage.
Gali looked at the Pohatu, a deep sadness cloaking her whole being.

I'm on the brink, I lost my self control
I didn't think that this would happen to me anymore
Just want to be a babe for once

"Sister?" Pohatu placed a hand on her shoulder. He tried to look in her eyes, but she looked away. He looked at Lewa, but he ignored the gaze as well. "He... he... No!" He backed away from his sister.
"We cannot win a war against something immortal. But it can be stopped. We must stay separate from now on." Gali spoke, her voice sore.

I can't explain the feelings that I feel,
I'm not even sure if they're for real
Doesn't work to end in sour tales

I have lost four brothers. Four is too many. Too many to lose is seven years. Pohatu sat down on his bed in his hut. It is completely agreeable that we must stay separate till we find a way to stop the poison from spreading. But my time alive is running short. I am on the last breath of life and I am lingering. Somehow, I linger in life. When death comes, I shall welcome it and be with my brothers once again.

Go to sleep so I can wake up
Wondering why things are this way
What the fuck did I say?
To make you hate me any way (you lose)

Pohatu sat down on his bed in his hut.
