Ly-Cilph

The Ly-Cilph are a highly intelligent, telepathic ancient race from a distant galaxy that evolved to transcend their physical form millennia before the evolution of humans.

They were not a highly technological civilization, but pursued knowledge and regarded understanding the universe to be their purpose.

Upon transcending from their physical form into a being of pure energy they travelled the cosmos, studying life wherever it arose.

They arrive at the Milky Way galaxy and start observing humans shortly before the start of the Trilogy.
