Ethan’s dorm room was dark, lit by the lamp on the desk. Sparsely furnished with no more than a desk, bed, and loveseat. Ethan, Alice, and Penny were together waiting in silence as the moment they were waiting for approached. The past few hours of excited speculation was finally coming to a head.
Ethan’s heart pounded in his chest as he looked at his twin sister Alice and his girlfriend, Penny. They had been through a lot together over the past five years at the Guild training campus, countless hours of practice and studying spent together. Tonight was what it had all been for. Five years since they had been Class Marked. Five years waiting to see what their Marks would resolve into and discover what Classes they had been granted.
Penny sat next to Ethan on the edge of his bed, her legs crossed underneath her and her hands clasped tightly in her lap. She had received her class a month early, becoming a D ranked Dark Weaver. She was eager to see what her friends would receive. Would Ethan get a defender class like they had spoken so much about? Would Alice end up a mage like herself or as she was hoping, something weapon focused?
Minutes left on the clock, Alice began pacing back and forth across the small room, her steps quick and restless. She had been born just a few minutes before Ethan and her Mark would be resolving first. Her hands twitched at her sides, as if the wait was driving her to want to spring into action.
Ethan took a breath, trying to calm his nerves. He could feel the weight of their expectations covering the room, weighing down both of them. Whatever happened tonight would determine their future as a dungeon raiding team. He glanced at his girlfriend waiting next to him, her dark hair falling down her shoulders, and she gave him a reassuring smile.
“Alright,” Ethan said, looking at the clock. How he managed to keep his voice steady despite the butterflies in his stomach he would never know. “Let’s do this.”
Alice nodded and turned to face Ethan as he stood. His ever so slightly older sister took a deep breath and closed her eyes. She focused inward towards the Mark on her back, awaiting the moment. You could see her twitch as she first felt it, the power surging in her Mark.
She opened her eyes, her mouth spreading into a wide grin. “Shock Blade, D rank!” She shouted. “I can’t believe it!” She spun around, lifting up the back of her shirt to show the others her new Mark between her shoulder blades.
Ethan felt a surge of happiness for his sister, seeing eyes filled with joy as she looked in the mirror at the Shock Blade Mark on her back. He’d known how much she was hoping to end up with a Striker Class, and Shock Blade was perfect for her. “You’ve been hoping for this Alice, I’m so happy for you.” He congratulated her.
“That’s amazing, Alice!” Penny exclaimed, her voice filled with joy for her friend. “I can already see you out there, kicking ass and taking names. Or should I say zapping?”
Alice laughed at Penny’s joke, her cheeks flushed with pleasure. Out of nowhere, she blurred across the room. “Surge! I have a speed skill!” She proclaimed, testing her new abilities. Holding out her hands, a loud crack of electricity rang out as it arced between her fingers. Her grin got even wider. “Shock. Maybe you’re right Penny, as lame as that joke was.” She teased her friend. “Oh I am just going to love this.”
Ethan looked back to the clock, seeing his moment was approaching. He closed his eyes, turning his attention inward towards his Mark. A sense of trepidation came over him, worry about what he might receive for a class. Something that wouldn’t fit with Alice and Penny, or maybe- His thoughts were interrupted as he felt the surge of energy in his Mark as it began to change. As the energy receded, he felt at it, searching for his class.
“Essence Bonder?” He questioned outloud, unfamiliar with the class title.
Moving to the mirror, her turned around and lifted up his shirt as Alice had done, looking at his Mark. It had resolved itself into an intricate circle, full of complex patterns. In the four corners sat empty circles, as if waiting for something to fill them in.
“Ethan? What is it?” Penny asked, seeing the look of confusion on Ethan’s face.
He hesitated a moment before speaking. “Essence Bonder. I’ve never seen it before.”
Alice leaned in closer, her eyes narrowing as she studied the mark. “What does it mean?”
Ethan closed his eyes again, reaching inwards towards the Mark and the abilities it would grant him. “It’s S rank.” he whispered, his voice full of disbelief.
Penny’s eyes widened in surprise, and Alice looked at him with a mixture of excitement and joy. “S Rank! What can you do?” Alice nearly screamed at him with excitement.
Ethan hesitated as he went over his newly granted abilities. “It means I can create bonds with others through essence. It’s a support class.” His voice tinged with a hint of shame.
Penny picked up on his tone. “Ethan, what’s wrong?” She asked with concern. “You’re S rank! This is unbelievable.”
Ethan paled as he continued reviewing his abilities, shaking his head as he continued. “The cost of my abilities is ... High.”
“What do you mean by ‘the cost is high’? Alice questioned him, picking up on Ethan’s odd behaviour.
He was at a loss for words, unsure how to describe what his class did. “It means that the bonds I create are sexual in nature.” Ethan finally spoke.
The room fell silent and Penny and Alice processed this revelation. Ethan could see the confusion and shock in their expressions, and a wave of guilt washed over him.
“I’m sorry.” He began to apologize. He could see all of their plans for forming a team together falling apart as he spoke. “I never wanted something like this.”
Penny reached out for his hand, holding it tight. “Ethan, it’s okay. Whatever it is, we can figure out a way to make it work.”
Alice nodded in agreement, but Ethan could see the uncertainty in her eyes. He knew she was thinking the same thing he was, the plans for their team that they had talked about for nearly a decade were shattering.
“But what does it mean? That your class makes sexual bonds? I don’t understand.” Penny questioned him as she felt the mood of the turn turning downwards.
Ethan began laying out how his class worked. “I can buff or heal, but I have to form bonds with others, without them, my skills are useless.” He hesitated. “The bonds are formed by creating ‘Essence’ with someone...” He trailed off.
“But what does that mean, Essence?” Alice asked him.
“It’s my class resource, instead of mana. I can generate it slowly over time, but the primary source of it appears to come from being ‘intimate’ with someone. The more I am, the more Essence is created.” Ethan croaked out.
They sat in silence, Ethan feeling a greater and greater sense of foreboding as it stretched. The implications were clear to all of them. His class demanded that he have sex with someone and he’d be useless on a team if he didn’t. That wouldn’t be a problem with Penny. They’d been together for years, now. But Alice? How was he supposed to bond with his sister?
“I’m ... going to go think about this,” Alice said, making your way to the door. “I’ll talk to you in the morning, okay?”
“Meet us here and we’ll go together to register your classes?” Penny asked.
“Uhm, yea, okay.” Alice responded, quickly making her way out the door.
Penny turned to Ethan, not sure what to say. The silence stretched on again. “I know this is crazy, but we can figure something out, okay? Classes all have crazy mechanics we can test out.” Penny spoke, trying to find a silver lining somewhere. “It’s already late, why don’t we just sleep on it and plan on finding some ways to test out your class tomorrow? You’re S ranked, there must be something great about your class, it can’t be all downsides, right?” She suggested, sounding like she was trying to convince herself.
Ethan nodded silently, beginning to get undressed mechanically. They climbed into bed and all Ethan could think about was how his class had ruined everything. The more he looked into his abilities, the more certain he was. Penny climbed over him to lay down, her head resting on his shoulder, started to trace patterns on his chest like he loved, trying to comfort him.
“Tell me about your class?” She whispered.
