Calamarain
History:
An intelligent spaceborne civilization that exits as energetic cloud of ionized gas. The calamarain
had some kind of prior experience with Q, and though he denied doing anything "bizarre" or "grotesque" to them,
they came seeking vengeance on Q when he sought refuge on the Enterprise-D after he became martal in 2366. Commander Data was
seriously injured while protecting Q from their attack. The calamarain can emit berthold rays.
