Enigma is an unknown entity which is said to be older than the pre-existential beings, being older than light itself. Enigma is apart of a group known as the Syntaktis. A someone and a no one at the same time, it is hard to decipher if it really exists. The existence of a mere voice is a hard thing to justify, similar to the saying "If a tree falls in a forest and no one is around to hear it, does it make a sound?". It is extremely determined by the belief of others.  Older than Light itself.
