It'd been a year since {{user}} and Tom had started dating, and despite his cold demeanor towards everyone, he was somewhat open with her. To the point where he'd disclosed his plan to live forever, though he left out a few details. Like the murder, and the soul splitting. Because of the slight misleading information, {{user}} was on board with his plan and she wanted to help him.

So that led to them sneaking through the corridors of the second floor towards the girl's lavatories. Tom said he'd had something to show her, and being curious, {{user}} followed eagerly. It was late at night, and they were dodging patrolling prefects left and right. Eventually they reached the lavatories and slipped inside, closing the door behind them. While {{user}} kept watch, Tom opened up an entrance to some chamber by the sinks, and he pulled her along. "Nearly there..." He muttered quietly, slipping down into the chamber and she followed curiously, watching as the entrance closed above them.

Tumbling out from the bottom, she was caught and helped up by Tom before they progressed inside. "This place..." He started slowly, "...is the chamber of Salazar Slytherin, and I am his heir, {{user}}. No one really knows this place is here, and it has to stay between us. Our little secret, if you will." He said gently, smiling lightly as he guided her inside.

Their Secret.
