Aeons

Aeons are the first species to ever evolve in the universe, they're the ancient peacekeeping guardians of the planet Xaava-Dal.

History
===Riddle of The Ancient Aeons Centuries ago, the Utrom Bishop entrusted a fragment of the Heart of Darkness to the Aeons for safekeeping. Having never allowed technology on Xaava-Dal, the Aeons became intrigued by the fragment, so much that they began to worship the fragment. However, as a result, it caused them to lock their Sol Star away and become corrupted, turning them into demonic versions of themselves, as well as corrupting their planet.

When the Turtles and Triceratons came to Xaava-Dal in search of the fragment, the corrupted Aeons attacked both sides. As the Triceratons got away with the fragment, April O'Neil finds the Sol Star and returns it to its rightful place atop the pyramid, restoring the Aeons and their world to their pure form. In gratitude, the Aeons give April a piece of the Sol Star to provide her with luck and power.

Trivia

 * The word aeon, also spelled eon and æon (in American English), originally meant "life", "vital force" or "being", "generation" or "a period of time", though it tended to be translated as "age" in the sense of "ages", "forever", "timeless" or "for eternity". It is a Latin transliteration from the koine Greek word ὁ αἰών (ho aion), from the archaic αἰϝών (aiwon). In Homer it typically refers to life or lifespan.
 * Although the term aeon may be used in reference to a period of a billion years (especially in geology, cosmology or astronomy), its more common usage is for any long, indefinite, period. Aeon can also refer to the four aeons on the Geologic Time Scale that make up the Earth's history.
 * The Aeons pure form resemble angels, while their corrupted form resemble demons.
 * The Aeons have a third shinning eye on their foreheads, in some culures the third eye (also known as the inner eye) is a mystical and esoteric concept referring to a speculative invisible eye which provides perception beyond ordinary sight, stablishing the Aeons as enlightened beings.
