Saturn Girl is mentioned but not pictured.
The "new Fatal Five" consists of the Emerald Empress (with the Eye), Indigo, Magog, Selena, Solomon Grundy.
The Empress tells Cameron Chase her origin story:
"I wasn't always an Empress. I was born alone, and not to much.Orando, my home, offered few professions to those on the street. I toiled in the court of our Duke, at his mercy, mind and body, for years...until the Emerald Eye of Ekron. I returned only once, but when I did, I did so not as a slave...but as a ruler. Vengeance unquenched, I hunted my family. The ones that abandoned me as a child.
"They were all long dead. All but one. And when I saw the man...shameful. Poor. A scoundrel...my father. After so long...I could not help but understand his desperation. I could not help but love him.
"And, just when I'd found him...the Emerald Eye showed me how I'd lose him. And that, I could not allow. My Emerald Eye received a vision, a deception created to convince me Saturn Girl had to die. It brought me here. I nearly destroyed the wrong person. But there was truth beneath the lie. In centuries, a battle between me and Supergirl will kill my father."
This account differs from the Classic Empress's story in one aspect. The Classic Sarya was from Vengar, not Orando. Otherwise, it's fairly consistent with what we knew.
However, I don't buy it for a second. I just can't see the Emerald Empress getting all misty-eyed about finding the father who had abandoned her (more llkely she'd be glad of the opportunity to torture him to death, and pissed that the others of her family hadn't survived). In addition, the Sarya I know wouldn't speak in terms of "almost destroying the wrong person." Collateral damage was never a concern of hers.
I don't have a problem with Sarya being born on Orando, or even finding the Emerald Eye there (Ekron was the name of a previous civilization, of which the Eye is a remnant). [Although I suspect the creators are conflating Vengar with Craggok, the medieval planet upon which Superboy found the Empress in Adventure 252, and substituting Orando for Craggok.]
Bear in mind that Sarya admits she lied to the other members of her Fatal Five, so she could well be lying to Chase as well.
Meanwhile, where's Saturn Girl? She could have this whole thing wrapped up in a few pages. Less, if she enlists the aid of, say, Jeckie and Mysa.
Hey, this storyline would make a great two- or three-parter on the Supergirl TV show, wouldn't it?
