Emily stood outside the door to the training room. Now what exactly did she want it to look like? ... she had used the Room of Requirement on a number of occasions when she was at Hogwarts, so she was familiar with how it all worked. Thinking hard, she imagined the room beyond the door to be spacious, with low lighting, not so that it would be dark, but not so that it was too light either, sort of in between. Emily also imagined ... obstacles, pillars and stairs, with a small arena in the middle. There were also dummies and old suits of armour, with red and white targets painted on their critical points... the head and heart.

Content with the image she imagined, Emily knocked on the door three times, and it opened.....

It looked incredible, exactly as she had pictured it. For a room that looked small on the outside it was super spacious on the inside.

Looking back to make sure the... what's his name guy was following behind her.

Taking to steps at a time, Emily descended to the arena.
"This is perfect," she said in a low voice.
Turning back to the gentleman she had managed to recruit to help her with her task, "Sorry... I didn't catch your name," she said, holding out her hand.
