Frisk walked past Sans through the archway in the back of the room. There, she saw a figure, cloaked in shadowy robes, with faces that looked to be screaming in agony on the edges. The figure glanced at her, and spoke, "Frisk Dreamurr. You have passed judgement and stayed true to your path. There are two options for you now. You can have the choice of having the life you dreamed about in the Underground, or, by saving these tortured souls, you will be able to shatter the barrier cutting you off from the modern world."
She looked around the room, noticing the souls immediately. One was a monster soul, a white heart facing down, while the other was a red soul, determination like hers. Looking back at the figure after a few minutes of thinking the choices over, she answered him, "I choose.."
Chara Riddle-Dreamurr was a strange case. In the 1940s she and her older brother Tom were at an orphanage, where the caretakers hated them. Then, one day, a man dressed in eccentric clothing came and told them that they were magical, and told them about Hogwarts, a school where they could learn to harness that power. Tom had gotten his letter, and Chara would be getting hers the following year.
It was after Tom had gone to Hogwarts when the caretakers had brought the orphans on a picnic over near Mt. Ebbot. To Chara, it seemed strange, but she brushed it off. Then, she had been chased and cornered near the entrance to the mountain. The other kids then pushed her around, laughing as she fell into the hole.
That was 30 years ago. Now, she learned that Tom had found out she died, and turned on a darker path, diving into the most restricted books to find a way to bring her back. She and her adopted sister Frisk had vowed to stop whoever had changed her brother like that. Now, since they were finally on the train to Hogwarts, they could finally start.
She was shaken out of her thoughts however, when a bespectacled boy slid open the door to her compartment, breathing hard. "Hey, mind if I hide in here for a bit? Padfoot won't leave me alone." Frisk shook her head, and gestured to a seat. He held out his hand, "James Potter," Chara and Frisk shook the hand, and told him theirs, "Frisk Dreamurr," "Chara Riddle-Dreamurr, pleasure to meet you." she drawled, much to her sister's amusement. James looked confused for a moment, then seemed to get it. "So what house are you in? I've never seen you around."
Chara answered for both of them, "We're transfers. Been out of comission for a while. I'm hoping for Slytherin. I've got distant relations to Salazar Slytherin, and maybe my brother could find me easier."
James looked surprised about the family, but to his credit he didn't sneer or trashtalk the house of Snakes. "Who's your brother?"
"Tom Riddle."
At this he paled, having heard from his best mate Sirius Black that Riddle was bad news for blood traitors and muggleborns. The girl called Frisk gave him a curious glance and he hurriedly explained. "My friend Sirius says he's bad news-not that I'm trying to get on your bad side-and that most purebloods are joining him in his ranks. Dumbledore-he's the Headmaster-doesn't like him. Apparently something about a lost sister...?" He trailed off and looked at Chara with wide eyes. She smirked, her crimson eyes almost glowing in the low light, "So you figured it out this early, huh?," she pulled out a knife "It's a good thing you won't decide to tell now will you Jamie-boy?" sje cooed, while Frisk was glaring at her sister and James was backing up against the chair, his tanned skin paling fast.
