>Setup is Briana and crew in BQverse are doing a mining scouting mission for the rebels with devices that can detect mineral and metal deposits
>Meanwhile in GGverse Jade Empress is searching for a magical artifact on the edge of Platinum City, a circlet made of what she knows as Orichalcum (but is really brass)
>she is summoning jade golems to do the dirty work, but is running low on available jade so she begins to summon familiars from other planes of existence. In a bizarre twist of fate, Briana is suddenly whisked away from BQverse into the mines outside platinum city
>Confused and disoriented, Briana is ordered to begin mining. Predictably she refuses and the jade golems move to restrain her. After a brief battle, Briana escapes, but her metal detecting device is lost in the fight
>makes her way into the city proper, getting weird looks because of her attire, not her tits. Silver Queen shows up to the scene she's starting to cause, and SQ's manner of speaking is really difficult to understand. A scuffle ensues, where SQ is easily subdued by Briana, it's barely a fight.
>GG intervenes, not with battle, but with diplomacy. She’s also sort of shocked to see someone who not only has huge tits like her, but even bigger ones. Briana lets SQ go and after a brief conversation fills GG and SQ in on how she got there. Learning about the evil of the Jade Empress, the three of them agree to put an end to her evil scheme
>meanwhile while all this was happening, Jade Empress had been fiddling with Briana's metal detecting device. After some fiddling and experimentation, she discovers its purpose, and uses it to pinpoint the exact location of the circlet
>by the time Briana, SQ and GG arrive in the mine, it’s too late. Jade Empress greets the trio with the circlet in her hands. Putting it on her head, she is flooded with arcane power and uses it to instantly summon MANY more jade golems to battle the trio.

>Using their gadgets and special moves, SQ and GG manage to fell many golems, where Briana uses her super powers to smash them to pieces. But it’s no use, the magic consuming Jade Empress is too powerful. The golems regenerate almost immediately, and even Briana is starting to tire. SQ thinks quickly and notices a rock formation in the shape of a seesaw. She has GG use some bombs from her utility pouch to collapse part of the mine ceiling onto the other end, the plan to launch herself at Jade Empress and nab the crown off her head in one fell swoop.
>Jade Empress reacts with unnatural speed though, and blasts SQ out of the air with a magical beam. Injured, GG takes SQ behind a rock formation for cover. Briana is almost out of steam completely, and the golems are pummeling her relentlessly. Things are looking grim, and as a last resort, SQ removed her Bands of Boudicca and give them to GG with instructions to have Briana wear them
>Using her deceptively keen acrobatic skills, GG hops over the tops of the golems over to where Briana is making her stand. A smoke bomb gives her enough cover to shove the bands into Briana’s hands and tell her to put them on. The Bands amplifying power can turn an ordinary person like Sarah Sterling into a super hero like Silver Queen, but for someone already significantly enhanced like Briana, the effect is much more profound. Pulsing with mystical power flooding from the bands, Briana destroys several golems with a wave of her hand, then leaps into the air after Jade Empress, her body glowing so bright that only the red of her bandanna is visible against the golden energy covering her

>Powered up Briana fights Jade Empress. The remaining golems haven’t forgotten about GG, and continue to try to crush her. GG battles golems on the ground while Briana battles Jade Empress in the air. The mystic circlet on Jade Empress’ head is powerful, but her frail, ancient body simply cannot channel enough of it to beat the super powered Briana. Eventually she yields, and Briana snatches the circlet off her head
>the few remaining jade golems instantly move to their master, forming a shield around her with their bodies. GG uses the remainder of her bombs to shatter them, but Jade Empress has already escaped into a rapidly sealing tunnel
>now with no foe, the power of the bands begins to overwhelm Briana. They were never meant to be used by anyone than a normal human, and wild lashes of divine power streak out from Briana’s figure as she screams in pain. It’s starting to collapse the cave, and GG dives into the maelstrom to save her. Flipping, diving, and rolling around the deadly cascades of energy, GG reaches Briana and undoes the bands. Briana falls to her knees, dripping with sweat
>GG returns the bands to SQ after making sure Briana is ok, and the three of them celebrate their hard-fought victory. Just one problem, how to get Briana back to where she came from? Fortunately, SQ knows someone who can help. While not a magic user, her friend Connie Cosmos uses her incredible scientific knowledge to ascertain the wavelength of Briana’s universe by measuring her. Using the circlet as a power source, a portal is opened to BQverse. A short goodbye and Briana disappears through the portal. SQ takes the circlet and snaps it in half, rendering it totally useless, concluding another wild adventure of Golden Girl.
