Star Trek: Defiant#19 is written by Christopher Cantwell and drawn by Angel Unzueta. The issue opens with a text piece of a Romulan intelligence briefing. Originating during the Dominion War, the piece paints a bleak picture, and suggests a wild plan: that the Romulans create a cloak so massive it could hide their entire star system.

Furthermore, tampering with their star causes it to destabilize, which will soon cause it to explode.
