Tren Krom (Being)

"You think me an alien... an 'other'... but I am of the substance of this universe, and I walked here long before you or even Mata Nui himself. Have you not heard the tales?"

- Tren Krom to Brutaka

Tren Krom was an entity created by the Great Beings long before Mata Nui ever existed. He initially watched over the universe, but was later exiled.

History
Long ago, before the Great Spirit Mata Nui existed, the Great Beings created an entity that was totally organic: Tren Krom. It was his job to keep the universe in order until Mata Nui was ready to take over. He did this, but was then exiled to a small island and fused to the rock of a cave so that he could not leave.

Some time later, Makuta Mutran was sent to meet with Tren Krom to ascertain his motives and goals. When Tren Krom linked his mind with that of Mutran, the latter gained knowledge of how best to strike at Mata Nui. For some reason, Tren Krom seemed intrigued by Mutran's mind, and so released him.

Later, in Federation of Fear, Brutaka's team landed on its island. Lariska was the first to detect it, hearing a wet, breathing sound, and something slithering. He then caused impenetrable walls of stone to spring up, and attacked Brutaka with a tentacle, dragging him into its cave. When Carapar attacked Tren Krom, the entity killed him with an eyebeam. When Brutaka and Spiriah told him of the danger to the universe (and him) from the Brotherhood of Makuta, he told them of his creation and past life. They tried to persuade him to help them in their cause, but he refused, as he was disappointed in them and their kind for bringing only anarchy to the universe that he had once watched over. He eventually released them, saying that no condemnation of his was worse that what they already faced: life in a broken world that they had created.

Physical Characteristics
Tren Krom was described as having an appearance so horrible that Brutaka had to struggle to maintain his sanity. He was completely organic, and apparently was mainly a scarlet, gelatinous mass, with tentacles for arms.

A description of Tren Krom according to Makuta Mutran:
"In the interests of writing a complete record, I should include every detail of my time there. In the interests of the sanity anyone reading this, I will not. Even when I look back now, I remember only a scarlet mass, a face that was not a face, tentacles lined with tiny, sharpened hooks, eyes that were little more than holes in a gelatinous skull, and that voice... oh, that voice made Makuta Teridax sound lilting and sweet."

Powers
The full extent of Tren Krom's powers are unknown, however it has been implied that he was immensely powerful. He had demonstrated the ability to link his mind with that of others, gaining their knowledge and giving them access to his. In order to keep Brutaka's team from leaving, he erected impenetrable walls of stone around his island. He could also fire beams of energy from his eyes that shattered the being they were aimed at. Tren Krom is said to possess great power nearing that of Mata Nui.
