Author's Note: Hello, Grab Bag/Story Idea Mark 2 is here! Thanks again to my Beta, Mr. Stark357!

Disclaimer: I don't own either Mass Effect or Lost Girl. If I did, I'd have tried to make the original ending to Mass Effect 3 satisfying from the get-go. Also, I haven't seen Season 5 of Lost Girl, so this is only canon up to Season 4. Sorry.

MASS EFFECT/LOST GIRL

"Trick, we need to talk."

The diminutive bar-tender looked up. The woman sitting in front of him was a dark-haired beauty known throughout the galaxy as a hero. He'd known her before all that, though, 'before she was cool' as the kids would say. "Bo," he said. "What brings you here?"

"Can't I drop by to say hello to my favorite grandfather without being compelled to by some catastrophe?" she asked.

"I learned a long time ago that you can't stay out of trouble, Bo. It's why my hair's going gray," the short man answered. The two looked nothing alike, but anyone watching the two wouldn't be able miss seeing the connection they shared.

"Well, at least it took a couple thousand years to get there," the woman replied.

Trick smiled. "I'm old, but I'm not that old. My two thousandth birthday isn't for a decade or so."

Had there been any aliens or humans in the establishment (unlikely, given that they were tucked in an out of the way corner or the Ward, and Trick didn't advertise The Dal, Mark 2), they might have been understandably confused. But, no one in the tavern, a strange combination of European rustic and Citadel Sci-Fi, was truly human. Nor where they alien in the way most thought of the term. They were Fae, members of a confederacy of strange, magical races who had hidden in the shadows of the human world for countless millennia. Looking around the room, Bo saw people she knew as Orges, Frost Giants, Fairies, and a one-handed Mesmer who stuck his tongue out at her from his position by the door. Alongside them were patrons she'd never met before, who could have been Aswang, Hyrdas, Baku or any number of things.

So far, though, there were no Wolf-shifters, Vampires, or Valkyries.

"You look like you could use a drink," Trick said, placing a glass for his granddaughter down on the bar.

She gave a weak smile and nodded in thanks. It had been almost 50 years since Lauren (after choosing to become a Vampire to stay with her forever) had been staked by a Dark Fae assassin, 65 since Dyson had been killed in a fight with a skinwalker, and about 170 years since Rainer, Hale, and Kenzie had all died as a result of that whole 'Doorway to Hel' thing. "Why do all my relationships have to end so badly?" she asked.

"You haven't lost everyone, Bo," Trick said quietly, placing his hand on hers.

"Yeah, but the one's I haven't aren't exactly going well at the moment," she said. "You almost died in the fight with the Garuda. Tamsen and I still can't decide what to do about each other, Liara's turned into the new Shadow Broker—"

"What?" Trick asked.

"Garrus turned into a vigilante on freaking Omega, I've met a new guy named Thane whose dying of some incurable disease, a new lady named Samara with a persecution complex even worse than mine, and I just learned that Kenzie is a Valkyrie now!"

"Well, she technically died in battle," Trick remarked. "I'm guessing you met her . . ."

"While I was dead?" Bo offered. "Yeah, that was about the only good thing about that. The Nain Rouge says hi, by the way."

"That's never a good sign."

"Apparently, the Reapers are coming, and we're all doomed. Why doesn't that kid ever have anything nice to say?"

"Brining tidings of comfort and joy isn't exactly in her job description," Trick replied. "I take it this is what you wanted to talk to me about? Kenzie and the Nain Rouge and," here he paused and looked around, "the Reapers?"

"Yes. No." Bo played with her drink. "There's something else; it's been bugging me for days, but, Trick I don't know if even you can help with this one."

"Bo, I've never pretended to be some kind of miracle-worker," the man who was once known as the Blood King, leader of the Light Fae, and broker of the Truce between Light and Dark said. "All I can do is listen and offer what advice I can; it's all any grandfather can do."

Bo nodded, absently. "When I met Samara, she told me that all three of her children were Ardat-Yakshi." She looked Trick in the eye as she spoke the next words slowly and quietly, "They're Asari Succubi."

"Succubi . . . What do you mean?"

"I know it sounds crazy but . . . I saw one of them. She could seduce anyone, drain away people's life force with sex, and use the energy to grow stronger."

"Amazing," Trick whispered. Alien Fae . . . Why haven't we heard of this before? If the Asari government knows they're real . . . ?"

"Because the Asari hate them," Bo said, slamming her drink down almost hard enough to crack the glass. "They treat the Ardat-Yakshi like lepers, Trick, force them to spend their entire lives locked away in these monasteries or being hunted down by their own people!"

"What?"

"Yeah, apparently the 'leading voice of diplomacy in the galaxy' are little better than Nazis when it comes to their own kind." Bo took another drink.

"I get the feeling these rants are leading up to something a bit more," Trick said, tempted to pour himself a drink.

"I could have been like them Trick," Bo said. "If Dyson, Lauren, Kenzi, and you hadn't been so supportive, I—I don't know where I'd be."

"That's the sort of idea my nightmares are made of," her grandfather admitted. "But, Bo . . . You do realize we're talking about an entire species here. Saving the Rachni was one thing; there were only a handful of them left. I get the feeling there are a lot more Ardat-Yakshi than that."

"I won't let that stop me," the woman said. "I'm going to teach the Ardat-Yakshi what it means to be a Succubus, and teach the Asari what happens when you mess with one."

Trick was silent for a moment, contemplating the woman who stood before him. Very few knew the name Ysabeau of Clan Fin Arvin, but everyone in the Citadel Alliance had heard of Commander Shepard. As she said, the Asari were about to learn a lesson they would never forget. "How can I help?" he asked.

BASIC CHALLENGE:

Commander Shepard is actually Bo, who decides it's time to help her Asari "cousins" learn to control themselves and live their own lives.

1. For whatever reason, she also has to introduce her friends to the Fae and reveal herself as a Succubus.

2. Samara and Liara are conflicted to say the least.

3. Kenzie is now a Valkyrie, although her "work" keeps her from seeing Bo much.

4. The Light and Dark still exist and still cause trouble.

5. Since Succubi need multiple partners to avoid killing them, this is probably going to be a FemShepxHarem story. Still, it's the writer's choice. Presuming anyone picks up this newest mutation from the pop-culture-irradiated nerd-caverns of my mind.

Sorry that it's a little short, I really don't know what to do with this idea. I just think it's good one, and I can't believe no one's explored it yet. Seriously, why hasn't anyone thought to do a crossover between Mass Effect and Lost Girl before? I am I the only one who's ever looked up the Ardat-Yakshi on the masseffectwiki? They are specifically compared to Succubi, and their powers match up pretty nicely to Bo's.

Admittedly, this is also kind of an excuse for me to do a Femshep/Harem story (I am such a perv). At the end of the day, FemShep/Liara is my OTP, but FemShep/Thane is a close second, and I kind of like FemShep/Garrus (FemShep is my head-canon in case you haven't guessed. Granted, she also a redhead, but what ya gonna do?), and making her a Succubus is as good an esxcus-er-reason as any to put them all together.

That said, I also REALLY like mixing supernatural elements into the Mass Effect Universe. I just get a kick out of seeing/imagining all these aliens going "How are you doing that!" This is a similar thing to what I said last chapter about Harry Potter, I think I may have a fetish.
