Legolas took Elsa through passage after passage until they were at the throne.
"Ada," He said.
"Legolas, who is this?" The king said.
"I am Princess Elsa of Arendelle. I followed a mist into this forest and that's when he found me." Elsa pointed to Legolas.
"Tell me all of what happened," The king said.
"Can't you at least tell me who you are?" Elsa asked.
"I am King Thranduil of Mirkwood. Now tell me all of what happened."
"Well, it's like I told Legolas. I heard a noise in the night. I got up to see what it was; it was an orb of blue mist. I followed it to a mirror at the base of a mountain, but instead of seeing my reflection, I saw a forest in it. But that forest was different from the ones in Arendelle. I touched the mirror, and here we are. I honestly don't know more than that."
Thranduil looked at Legolas, and back to Elsa. "Well, if you like, you can stay with us until you know what to do," He said.
Legolas took Elsa to an unused bedroom. "You can stay here. If you like I can show you the forest tomorrow," Legolas said.
"Um, sure, thank you." Elsa sighed. "I have to get home," She said to herself. "So, Legolas, do you know how I could get home?"
"No, but I might have an idea. It is said that there's a place to the south of Mirkwood that can grant a person's one wish. The legend says that there is a lagoon where, if a person truly wishes with their whole heart for it, it can grant that wish. But before we go on some quest, you should see Mirkwood. It is a beautiful place."
"I'm sure it is, but I need to get to Arendelle. My sister will miss me. And everyone will be searching for me. I need to get back."
"Are you sure?" Legolas looked deeply into Elsa's eyes and smiled slightly.
"Fine, but as soon as I've seen this 'Mirkwood' then I want to go to Arendelle!"
"Very well, but for now you need your rest. Mirkwood is large; we will be gone for several days." Legolas left the room and Elsa alone. She looked around. It was large with elegantly carved furniture. The color scheme was grey and light blues. She climbed into the large bed and soon fell asleep in its softness. She didn't wake that night.
The next morning Elsa was awaken by Legolas. "Come, we need to leave early if we want this to be as short a trip as possible."
They had a small breakfast and Legolas had a pack brought to them. He brought her to the gate where they found Thranduil was awaiting them. "Where are you going?" He asked.
"I'm going to show her Mirkwood, ada," Legolas said.
"Be careful if you enter the dark," The king told them.
The prince and princess left the city and entered the forest. The day was sunny, warm, and in general it was nice. They walked around the forest for a few hours. Suddenly they heard a noise behind them. Legolas spun around with an arrow knocked into his bow. Both of them were surprised at what they found.
