A black cat stood before Anna's castle. Elsa had left the kingdom and returned to her ice palace on the North Mountain, leaving Anna in charge of the kingdom. But Anna had spent most of her time in the castle. The cat walked through the gates and jumped onto a window sill and jumped from balcony to balcony until she reached Anna's bedroom window. She pawed at the closed window and Anna left her in.

"Oh, what am I going to do?" Anna asked the cat. The cat cocked her head as a sign of comprehension about Anna's emotion. "Should I go to see Elsa? She would be able to help me." Anna stood up and paced the room.

"But I would place Elsa in danger if I saw her. I have to stay here. You seem intelligent. Can you get Kristoff?" the cat strangely nodded and leapt out the window. She returned a bit later with Kristoff.

"Is everything alright?" Kristoff said.

"Not really," Anna sighed. "Can you keep a secret?"

"Of course."

"I think I'm becoming like Elsa," Anna said.

"How?" Kristoff said. "What do you mean?" Anna twirled around. A circle of flames erupted around her. Suddenly, they disappeared.

"That's how," Anna said. The black cat's eyes widened.

"I knew there was something off about you!" a voice exclaimed. It was coming from the cat. Both Kristoff and Anna stumbled backwards. The cat spun in a circle and after a full rotation, a girl stood there.

She looked about Anna's age and had long black hair tied in a single braid.

"Who are you?" Anna demanded.

"My name is Carella," the cat-girl said. "And you and Elsa are like me. We are part of a race called Seni. There aren't many of us, but we exist. We each have original abilities."

"What's your ability?" Kristoff asked.

"All of them. I come from a line of Seni royalty. So if there were more Seni, I would be Seni princess. I have fire, ice, life, death, and so on," Carella explained.

"Death?" Anna repeated. Carella nodded.

"I don't use it very much," Carella assured. "But your power would explain the searing heat outside. I can help you control it. And training with me would be more effective than learning how Elsa did. Would you like me to train you?" Anna and Kristoff looked at each other. Slowly, Anna nodded.

"Yes," she said. "I think that would be best."
