This wasn't as bad as I thought it'd be!
Diana is teleported away to help the Star Sapphires combat a new foe. It turns out the new foe is one of the Dark Pantheon, the "God of Love" named Karnell. In the previous battle, he killed the Star Sapphire's leader (not sure if she was a new character or not). He represents the darkest and cruelest aspects of love.
In full Star Sapphire regalia, Diana goes to fight Karnell and finds out his backstory. He used to be a human in the Dark Universe until his leader, called King Best (awful name), plucked him from his tragic, abused life and made him into a god. Diana is eventually able to overcome Karnell and defeat him with the help of the other Star Sapphires.
When she returns to Earth, she finds one of the other Dark Gods heading straight for her.
While it seems like nothing happened beyond the fight between Diana and Karnell, it was actually a pretty interesting story. It had some of Robinson's dialogue problems of course, but I'm finding myself suddenly more interested in the dark pantheon. I like that they made the dark god of love male, though he looks quite androgynous. I've never been a big Green Lantern fan so I don't really know much about the Star Sapphires, but I love the name Miss Bloss. And they're not as scantily-clad as I remember, thank god. I did also like how the art shifted from standard comic booky to full-blown painting.
Other things to note:
• Wonder Woman serving as a Star Sapphire during post-Crisis's Blackest Night storyline is still in canon, as is Maxwell Lord who was briefly seen in a flashback image. So we can assume her snapping of his neck is also still part of the current continuity.
• No Carol Ferris, though she was mentioned by the others. They said she was "unavailable."
• There are 13 total Dark Gods evidently. Six of them, including Karnell and King Best, were taken from their world after Dark Nights: Metal. Seven remain in the dark universe.
