Prompt (by friend): What if Sam succeeded in closing the gates only it had a similar effect to shutting down Heaven and locked the souls out along with booting Lucifer and/or Michael from the cage?

Warning of angelcest relationship and female Lucifer.

Also, for context, the angels have tails and other animal traits that are loosely mentioned.

This would never begin to fix any of the damage that Crowley had done, they both knew that, and yet it was a start. Damn these emotions. Damn this humanity. The warehouse stank of mildew and his body -not his meatsuit- hurt all over. Nowhere more than the spot on his neck where that bloody needle had been jabbed multiple times over the last hour.

"Exorcizamus te, omnis immundus spiritus, hanc animam redintegra, lustra."

The notebook was tossed to the side by the tall hunter and Crowley watched patiently -hopeful- as Sam approached him. The younger Winchester cut into the palm of his hand, blood dripping forebodingly from the end of the blade and his palm. There were at least a thousand things he wanted to say, that he wanted to do, and none of them would ever fix any of this. There were so many mistakes that he'd made in his long life, so many things he'd done to people. The count of bodies… lives he'd ruined. The things he'd done in his sad miserable life hadn't been good things.

"Do it, Moose." Crowley spoke, voice cracking with unbridled emotion as a hand came down over his mouth.

"Lustra!" Something ripped through him with that word, tearing him apart from the inside and making him cry out in unspeakable agony. Power ripped through him, tearing him from where he was seated, and leaving him in a momentary state, staring down at the younger Winchester and himself in the middle of some rugged ratty warehouse. Then he was seated again, inhaling a sharp, sudden breath and…

"Sam!" Dean's voice cried from the entrance as Crowley became aware of a heavy weight laying on his legs.

Lucifer brushed her fingers across the mattress of the manifested bed, watching Adam Milligan's soul twitch and shudder as it lived through memories. Maybe they couldn't make up for everything that had happened to everyone on their behalf, but they could at least try to help Adam. One of these days they'd be able to free him. It might take decades but they would do it, free him from the worst place in all of Creation. Send him back to Heaven where he belonged.

"Luci!" Lucifer was drawn from her distracted thoughts as she turned, Michael coming through the artificial door before it all crumbled away. Lucifer opened her mouth then shut it as the Cage began rattling around them. What was happening? Why… Michael encased Lucifer in his wings in a panic and Lucifer shivered slightly, allowing the gesture to comfort her before kicking into panic mode.

The Cage was collapsing. It was crumbling apart in a way that shouldn't have been possible. Nothing could destroy this Cage, nothing short of God himself and God didn't care. Especially about her. "Do you think someone is freeing me?"

The clear answer was 'no'. No, they would not take Michael from her. Even in this hellspace, there was nothing that could steal her archangel. White wings spread behind her as she sheltered Michael beneath them, covering him as a bar fell from the top of the Cage, plunging downward at speeds that would surprise even Gabriel and causing her to cry out in pain as it ripped through the sensitive flesh of two of her overlapping wings.

Michael was safe.

"Lucifer, you ignorant-"

"Call me a human and I will destroy you." Lucifer warned without any true threat as Michael spread his wings, wrapping his arms around her torso. "What in God's name are you doing, Michael?"

"Don't blasphemy, Lucifer." Michael chastised her without any of the true purpose behind the words that had once existed. Then Michael was pulling her into his Grace, launching himself upwards with Lucifer in tow. Adam was with them too, wrapped in the fray and clinging desperately to Michael's leg.

"There is no way-" Michael cut her off by wrapping one his six tails around her leg and squeezing tightly in a long ago implanted signal of 'shut up'. Lucifer was just about to ask something else of him when Michael screamed, becoming a massive weight that sent the both of them plunging downwards. "Michael!" Lucifer shouted, catching her mate's weight and fighting to hold the both of them as she continued their flight upwards. No.

This couldn't happen. Not here. Not now.

"If you die on me now, Michael, I will kill you!" Images of what was supposedly her dead at the hands of Michael flashed across her eyesight as she fought to hold him to her chest. That hadn't been right. That had been God's plan. Not the reality of the situation. Michael would never kill her and neither of them would die. It was an immense trial for her to carry God's oldest Archangel under the strength of only one set of fully functional wings. The biggest hope was when he glanced down, saw Michael's tail wrapped tightly around Adam. Michael was alive. Lucifer had no idea what was wrong with him but Michael was alive and he was holding onto that soul like a lifeline, Lucifer could see him draining it of its energy and for the first time in a thousand years Lucifer couldn't find himself to care for the soul. "Mikey, wake up. Please wake up." Lucifer whispered as they shot out of Hell.
