To Lyger 0: Unfortunately, that would probably require a degree of familiarity with the Rabbit Miraculous that none of them yet possess. And some indication of when the Tarasque last appeared. As it is they have neither; hence going to the one alternate timeline they know and hoping they strike gold.
To yellow 14: That is a good question. Nothing says that it didn't appear in the "RooT"-verse timeline. However, the two timelines have taken wildly divergent paths since Adrien and Marinette returned after "Running out of Time."
"I am Solo Act! Bereft of my family I may be, but I will not be the only one left alone in this camp!"
Eyes wide in shock, Rugindo Leoa dove to one side, narrowly avoiding a beam of black energy from the figure in front of her. Face pale, eyes black, dressed in what appeared to be a black mourning dress, the woman sent another beam of the black energy at Rugindo Leoa, anticipating where her dive would end. Rugindo Leoa rolled to her feet and whipped her short sword around with moments to spare, slashing at the mean and deflecting it away from herself to one side. Her sword sizzled where the energy hit it, but she didn't have time to think before another energy blast darted out at her. Within moments, Rugindo Leoa was spinning her short sword constantly to block the endless barrage of energy beams. "What the hell is this thing?" she yelled.
"I–I don't know!" She could see Rapeto running toward her from the far side of the camp. "This sure as hell isn't that same shadowy creature we fought in Lesotho!"
"Where did its powers come from!?" With all her attention focused on protecting herself, Rugindo Leoa couldn't spare so much as a glance at the impact of the black energy. Her gaze fixed on Solo Act, she slowly sidestepped in a wide arc, spinning her short sword as she went. Solo Act moved with her, sending more and more beams of her energy out in all directions. One struck a tent, which instantly disappeared in a puff of black. Rugindo Leoa stared at the point where the tent had been for a moment, confused. Her short sword dropped slightly.
"Look out!" Suddenly Rapeto slammed into Rugindo Leoa from the side, knocking her to the ground. Something black flashed in her peripheral vision.
Rugindo Leoa landed on her hip, rolled over, and surged to her feet, staring back at the spot where she had been moments before, but Rapeto was nowhere to be seen. Instead, all she could see was Solo Act, standing with her hands out, turning this way and that, sending blasts of black energy in all directions. People and tents disappeared left and right, vanishing in puffs of black. Already most of the tents closest to Solo Act had vanished, leaving nothing but empty space all around. Civilians fled in a blind panic, even as the African heroes raced toward the disturbance. As Rugindo Leoa watched, a black beam struck Harba, who disappeared in a puff. Her mouth fell open in horror, staring at the spot where he had been moments earlier. Solo Act turned in her direction, and she dropped lower, narrowly avoiding another energy beam. Spinning to one side, she crouched down, scanning the area around her for cover. "Rapeto! Harba!"
"Where are you!?"
Rugindo Leoa cocked her head in confusion, hearing Rapeto's voice clearly through her communicator. An energy beam nearly caught her in the shoulder, but she deflected it into a box of medical supplies with her short sword. "I'm… right where I was!" she informed him briskly. "Where are you?"
"I–I haven't moved!"
"Where is everyone!?" interjected Harba. "What's going on!?"
Rugindo Leoa furrowed her brows, staring at the spot where Rapeto should have been. But nothing was there. "I don't see you! Do you see Solo Act? Right in front of you?"
"No…"
Rugindo Leoa dove to one side, hiding behind the medical tent. Solo Act stalked closer. "What do you see, then?"
"I see tents… the medical tent is right there…"
"I'm hiding behind the medical tent," she told Rapeto, edging around it in the direction opposite where she had last seen Solo Act.
"I don't see you!"
"Wait… how many tents do you see?" Harba demanded.
"Um… seven, including the medical tent."
"Just in this area?"
"Just around the medical tent."
"But… I only see four…" Harba hummed.
Rugindo Leoa groaned. "Is that really important now?" she demanded. Solo Act stepped around the medical tent, and Rugindo Leoa backpedaled away from her. Solo Act raised her hand and shot another black beam at Rugindo Leoa, who deflected it into the side of the medical tent, which disappeared, leaving her in an empty clearing where there had previously been at least a dozen tents, including the medical and dining tents, to say nothing of the hundred or more civilians. "Now the medical tent is gone; do you see me now?"
"Wait… it's not gone! It's still there!"
"There's nothing here!" she retorted, spinning around through a backward cartwheel as energy beams streamed around her to either side.
Harba gasped. "It's got to be a trick! We're all seeing our surroundings differently!"
"What are you talking about?"
"The view hasn't changed for me at all," Harba explained quickly. "It's exactly the same as when the beam hit me! Has your view changed, Rapeto?"
"No…"
Rugindo Leoa twisted in midair to avoid another beam and bumped into something that deflected her away. Looking back, she couldn't see anything there. "Hang on…" Rugindo Leoa dove away from Solo Act, ducking around behind a stone column and looking out as Solo Act picked her way around where the medical tent had been, sidestepped around the spot where Rapeto had gone missing, and strode toward her. Rugindo Leoa narrowed her eyes suspiciously. "Bronto-Beam!" she ordered Rapeto.
"Are you sure?"
"Do it!"
Rapeto groaned in annoyance. "Bronto-Beam!" A sphere of empty space right beside Solo Act lit up a blinding white. Rugindo Leoa flinched, squinting at the light. Standing next to it, Solo Act covered her eyes, crying out in surprise. Rapeto let out a pained shout as the light began to fade. "And now I'm blind, too," he grumbled.
"Oh, son of a bitch!" Rugindo Leoa cursed, hurling her short sword at the sphere, just as the glow disappeared. The golden sword struck something rubbery and bounced off.
"What happened?" demanded Harba.
Gunfire rang out from the cliff above the refugee camp. Rugindo Leoa turned in that direction and almost missed the flash of black from Solo Act, lancing straight toward her. Leaping through the air in a back-flip, Rugindo Leoa barely managed to contort herself around the black energy. She smacked face-first into an invisible barrier, bounced up into the air, and rolled off of it, dropping low to avoid Solo Act's notice. She heard another volley of shots; several struck the rock columns scattered around the valley, sending tiny stones deflecting in all directions.
"There are people on the top of the cliff!" called Buq Hayij over the communicator.
Rugindo Leoa landed in a crouch, one hand on the ground, narrowed eyes focused on Solo Act, who continued to stalk toward her. Taking in her surroundings with her peripheral vision, Rugindo Leoa spotted two of her miraculous users near that area. "Delwer, Cadaabta Ey, north cliff face. Buq Hayij, you're with me!"
"What about us!?" Rapeto cut in agitatedly.
Rugindo Leoa frowned. "You're in some sort of bubble," she explained rapidly. Try to break your way free!"
Solo Act scoffed, sending a blast of energy at Buq Hayij, who dove to one side to avoid it. "As if having other people around can really help you now! You are going to lose – I'm going to take the miraculous, and then everything will be put right again! If you would just hand them over, this could all be done – we would no longer be solo!"
Rugindo Leoa's jaw clenched. "That's not the way to fix things!" she called, ducking another black beam. Buq Hayij rolled to her feet, planted her fist on the ground, and charged Solo Act with a bellow. At the same moment, Rugindo Leoa leapt into the air, flipped around an energy beam, and pushed off the rock column behind her, launching herself at Solo Act with her short sword outstretched. "There's got to be a better way to do this!"
Solo Act sidestepped to avoid Buq Hayij's charge and ducked below Rugindo Leoa, grabbing her leg as she passed and swinging Rugindo Leoa around into Buq Hayij's back. Rugindo Leoa cried out, but Buq Hayij couldn't move fast enough to avoid the collision. The two landed in a jumbled heap, and Solo Act sent a beam of energy at Buq Hayij. Lunging forward, Rugindo Leoa batted it right back at Solo Act with her short sword. Solo Act stumbled backward to avoid the energy beam, caught herself before she could fall over, and glared at Rugindo Leoa. "There is no other way! Everyone and everything I love is at home, and you have the power to undo all of this!"
Rugindo Leoa groaned, dodging out of the way. "I don't exactly disagree!" she retorted. "I'd just love to have all of you back where you belong. But that's not happening – not this way at least!"
"Give me the Ladybug and Cat Miraculous!" shrieked Solo Act.
"Why the hell do you think they would give you what you want?" Rugindo Leoa demanded. "Do you think Ladybug and Cat Noir don't want to help you get home?"
Solo Act loomed over her. "If they did want to help us return, they would have done it already!"
"That's not how this works!"
"What do you know of how this works?"
Rugindo Leoa swung her legs around and drove them into Solo Act's gut, sending her crashing backward away from her. Solo Act fell back into something which gave slightly under the weight and bounced back, pushing Solo Act back toward Rugindo Leoa. Rugindo Leoa rolled backward and scrambled to her feet, baring her short sword in front of herself as Solo Act lunged at her, arms out wide. Buq Hayij charged in from the side, tackling Solo Act and throwing her away. Midair, Solo Act turned one of her hands on Buq Hayij and sent out a beam of energy that caught her midstride. Rugindo Leoa caught a quick glimpse of the surprise on Buq Hayij's face before she vanished from sight.
"What on earth–?" Buq Hayij grunted; through the communicator Rugindo Leoa could hear her striking something with her fists.
"Try using your horn on it!" Rugindo Leoa ordered her. "And then see if you can find Rapeto and Harba!"
"That bitch hurt my son!?"
"I'm fine, umi." ["Mother"]
As Solo Act pulled herself up off the ground, Rugindo Leoa quickly turned to take in the chaos surrounding them. The Miradouro da Lua almost looked as it had only a few days ago, before this whole ordeal had started, before her temple had been forced to play host to these refugees. A handful of tents still dotted the landscape, the odd piece of garbage still littered the ground. But the majority of the tents had vanished into thin air. She could see a few refugees still watching from a distance, hiding behind rock columns for cover, but far fewer. Her stomach clenched. This was what she wanted to get back to: before the Tarasque had forced the Parisians into evacuating, before one of her country's most scenic vistas had been turned into a refugee camp. Before she had been called on to fight villains on her temple's very doorstep.
Solo Act rose to her feet, brushing off her black mourning dress, and dropped one foot back, glaring at Rugindo Leoa. Raising her short sword, Rugindo Leoa tensed to spring.
In her peripheral vision, Rugindo Leoa tracked Cadaabta Ey and Delwer as they sprinted up the path out of the valley, toward the distant black specks lining the cliff. The flashes of gunfire intensified as the two heroes crested the ridge. The gunmen retreated away from the cliff's edge. The earth rumbled; Delwer had raised a small line in the ground to give them cover. Cadaabta Ey's whip cracked, and the gunfire petered out. Rugindo Leoa let out a breath, grinning manically at Solo Act. "I guess you are left 'solo'!" she taunted her, eyes flashing.
"What difference does that make?" Solo Act retorted. "I am already left alone; why should it be any different now?"
Suddenly Delwer gasped.
"I don't know what it is, but – Cadaabta Ey can't move!" Delwer shouted. "There are people here – brown robes! I–"
Rugindo Leoa's eyes widened. Dark Acolytes! "Stay away from them!" she ordered, spinning to avoid a black beam from Solo Act. Delwer didn't respond. How were her miraculous users supposed to stand up against villains with weapons specially-created to nullify miraculous abilities!? Scanning the area, Rugindo Leoa's gaze settled on Aisha and another Initiate running in her direction. Pointing up at the bluff, she yelled, "Help them!"
