Star Power and the Mystery of the Zel Gux Dynasty is the 3rd story arc in Michael Terracciano and Garth Graham's Star Power series. The second arc ended with Dancia's powers back in working order and mercenary scumbag Black Hole Bill being sent off to what will apparently be a very unpleasant imprisonment. In the process of rebooting their powers (flying through a solar flare) the artificial intelligence that comes with the Star Power - which Danica named "Mitch" - sensed a signal from another Star-Powered Sentinel in the vast network meant to connect all of them, the first and only one he'd detected so far.
This story starts with the signal going silent, but Mitch tracing it to a star system where a mysterious group known as the "Zel Gux Dynasty" traveled from world to world, sharing knowledge with the inhabitants. The Zel Gux themselves are long gone, but their ruins are considered significant, so it has to be treated as an archaeological expedition (which Graham highlights with the cover to the first chapter, where Danica is rocking an Indiana Jones look.)
Each world turns out to have a different puzzle or challenge, each requiring certain things from Danica, though not her love of puns. That's a bonus reserved for her friends and coworkers. In addition, the variety of worlds give Graham opportunities to draw different aliens and civilizations. One group may be rock-people (who have commercialized their ruins to their maximum extent), another look like red pandas and live in homes built in the trees.
Danica brings along the same 3 members of the security team that became her friends in earlier volumes, plus her supervisor, Dr. Brightman. They take a backseat here, acting mainly as sources of levity in between the adventure sequences. Instead, Terracciano focuses on Beena, thus far an ancillary character, albeit one very excited to interact with Danica at any opportunity. Beena's an archaeologist, and an expert on the worlds in the Zel Gux Dynasty, so she's assigned to assist. Except as Danica solves the challenges without her, Beena starts working even harder to figure things out first. She means to show she's useful, but comes off as egocentric, especially to Danica. So that has to be addressed.
Terracciano also brings back the 3 Void Angel pilots that tried and failed to kill Danica as soon as she got the Star Power. Despite the Void Angels being gone, the Countess who hired them locked up, and the three of them being on their own, one is still hellbent on finishing the job. One seems willing to go with it, just follow whoever makes the most forceful argument, and the other Burke, seems increasingly hesitant to pursue this.
The story also jumps periodically to an extended conversation between the Countess and a member of Psychological Ops (a "psi-cop" in popular parlance.) It highlights circumstances outside the Millennium Federation (which the book delves into further in volume 4), as well as the Countess' mindset, but also teases out the history of the Star-Powered Sentinels while Danica and her friends track down these clues. I think the Psi-Cop is a little too confident about the Federation's stability, given the universe's trends towards entropy, but the series in general emphasizes hope and the value and strength of cooperation, so it's understandable.
I think this might be my favorite Star Power storyline. Maybe because it's more of a straightforward adventure. While it reveals some backstory, we're past the origin story. It's not as much a body horror deal as volume 5. The Void Angel Trio are a threat, but don't dominate the story, and neither does the subplot about Beena's need to impress people with how smart and useful she is. It feels like lower stakes, but that makes a change of pace from most of the other volumes, that have long stretches of life-or-death situations. It takes advantage of its setting in a futuristic interplanetary to offer differing settings, architecture, aliens and cultures. Casual worldbuilding, which lets the story focus on the puzzles, which are their own kind of clue to the backstory of the Sentinels.
