Ascendant

The Ascendatns are a race of Religious Zealots that are intrinsically linked with The Eav'Oq,the Bajoran Race, and the Prophetsof Bajor.

Physiology
The Ascendants are a tall race of Humanoids, who have a chitinous outer exoskeleton, akin to armor. Their eyes are gold and have no pupils. Their Blood is also a golden color, but upon healing becomes grey and mends the exoskeleton together. (Star Trek: Rising Son)

History
Not much is known of the Ascendant race. First encountered by Opaka Sulan on the moon Prison of the Ennis in the Gamma Quadrant, the Ascendants seem to be a race of beings that are in constant search of their own gods and those who worship them, if only to destroy both.

During Captain Kira's Visions, the Ascendants once used to be a race that traveled in large groups, intent on destroying those who worship the Bajoran prophets. They threatened the Eav'Oq, calling them Unclean, and proceeded to destroy the fortress the Eav'oq occupied. DS9:Warpath(Although this was all a dream, the historical facts of the Bajoran Army were similar to past indications, so we can assume that the ancient Ascendants were outfitted as Described in Warpath.)
