Creatures from Gene Roddenberry's Earth: Final Conflict,

In a taelon's natural state it is a translucent, blue ball of energy. For humans sake they take on a more human form something between The Buddah and Queen Nefertiti (as Majel Barrett Roddenberry puts it).

Taelons are also genderless and incapable of reproduction due to genetic tampering in an effort to advance their eveloution. Taelons are also connected by a somewhat telepathic network called the commonality, in which the will of one taelon can not take an action that the entire population does not agree on... or so it was intended.

Taelon language has no past or future tense, is sounds to a human like whispered singing.
