Fog does disperse slightly, but pulls himself together and keeps coming. The ranged attackers are all firing on the Empire capes, but Gren's glowing green weapon is the most visible target. Fenja lunges, not for Citrine Mage but for the stunbomb, both she and her spear increasing in size. Menja rushes ahead of her and engages the close-range fighters.
The stunbomb shrinks when the spear passes right through it. Citrine Mage applies just enough of telekinetic shove to Fenja to keep her from following up the attack, ascends, and starts charging it again. With her spare concentration she applies various shaker-type effects on the Empire's capes - the immobilization field, elemental things, telekinetic shoves, shields getting in their way, and so on. Watching Purity all the while.
Everything has a fraction of the effect it should on the giantesses, but the same does not apply to whoever they're fighting. They drag Aegis, Armsmaster, and Dauntless into the immobilization field, where they're much less slow than their opponents. They start exchanging blows. Triumph shouts that he can keep Fog occupied, and then shouts, the sound waves driving the mist back. Gallant alternates blasts between Fenja and Menja, to little effect.
The stunbomb is now large enough that she gives it a decent chance to shut down Fenja or Menja. She picks the one that seems easier to hit, and hits them with it.
While that battle is ongoing, and going badly for the Empire, Purity steps out the window. She's glowing brightly, and raises a hand. Light spirals out, blasting Triumph to the ground, then Gallant, then Aegis. Dauntless' shield blocks one with its own white light, and Armsmaster is surprisingly hard to hit. The next blast is at Gren.
Time to be more mobile. Gren starts dodging further attacks, filling the air with a hopefully overwhelming quantity of stunbolts, flitting around and trying to get Purity to make a mistake.
With Gren dodging and the others down or occupied, Purity starts talking.
"You attack me now? I wanted to clean up this world, same as Kaiser did, and do it without the drugs and extortion. With Krieg and Hookwolf gone too, I could maybe even get the whole Empire on board. We don't have to be enemies, but if you all insist then I'll just have to win."
She and Dauntless blast each other. Dauntless goes down.
She blasts into the building, thankful the steelwing is relatively compact, and seeks out Othala. Invulnerability probably means she's doing it.
She spots Othala easily, thanks to her cape-detecting senses. Purity fires at the steelwing, not caring for the property damage if she misses, and keeps talking to Armsmaster. Othala runs for the nearest window.
The steelwing takes a glancing blow and remains flyable, if less so. The blow Othala takes from a rain of stunbolts is not glancing.
Othala collapses. If Gren returns outside, she'll see Purity and Armsmaster still talking, neither moving against the other, while Triumph holds Fog at bay and Aegis gets coming back no matter how often Menja hits him. Fenja starts to get up, and Armsmaster gives her a small dose of whatever kept Lung down.
And since Purity shouldn't be invulnurable anymore, Citrine Mage can go back to trying to get a stunbolt on her.
Armsmaster calls out orders, "Gallant! Aegis! Get back to base, it's under attack." He gets back to dueling Menja, while Dauntless and Citrine Mage blast at Purity.
(stunbolt, stunbolt, gust of wind and smoke, stunbolt, stunbolt, flashbang bolt, stunbolt)
Menja lasts longer than her sister did, but eventually her opponents wear her down enough for the repeated stunbolts and Halberd jabs to bring her down. Purity, between blasts, grabs Othala and flees.
A shield forms in front of Purity's flight path. If this next round of stunbolts doesn't get her, it'll be better to save her mana than to keep chasing. She's already used quite a bit.
She tries to fly around the shield, and fires on it when she can't. She blocks as many stunbolts as possible with Othala's already-stunned body. While trying to fly away, she calls back "it's true! Ask Armsmaster!"
She radios Armsmaster. "Purity's gone, can't catch her, Steelwing's too damaged. Is HQ still under attack?"
"Faster to ride there. Should probably re-stun and foam everyone before we leave. Don't want the rest of 'em to get up. D'you know what she meant by 'It's true'?"
Not having the time for Armsmaster to try devices against Fog until something reverts him to normal, Triumph's sound waves force Fog's form into the back of an airtight containment van. He and Citrine Mage ride with Armsmaster. Dauntless is a speedster in his own right. Their PRT backup moves in to collect Menja and Fenja, while the capes rush back to the PRT HQ.
"I've got plenty of juice left, by the way, just can't fly well without a Steelwing. Triumph, when we get there I'll give you regen or invulnurability, your choice - I'll probably lose Othala's power before the day's done, but I still have it for now."
When they arrive, there are PRT personnel surrounding the building and bringing people out. The people being taken out are unconscious but apparently uninjured. "They've got the Director," Miss Militia informs Armsmaster when they arrive. "Released everyone else, and aren't interfering with rescuing unconscious victims. They knocked out everyone on the lower levels, even Lung in the cells, and say they're going to bring down the building."
Gallant gets back from being flown around the building by Aegis. "They're in one of the middle levels, the darkness on the roof is a distraction. They have to know we're here, but aren't worried about whatever their plan is being disrupted. The Director isn't worried either, for what that's worth."
She switches to a whisper spell. "I think she might be able to hear through them. She put thin webs all over the place, and there's mosquitoes or similar on most of us, tracking our position... No clue how she can keep it all straight in her head."
"We've been assuming they'll know as soon as we try anything," Miss Militia says. "Good to have confirmation. We didn't want to go in in force until everyone is out, especially Lung, in case they were serious about bringing down the building."
