"Interesting," Luna said, after touching her horn with Clarity's, "I've looked at the remnants of your dream. It was sent by Raven himself."
Clarity looked at her. "Does that mean something?"
"When the empire initially reappeared, the crystal ponies were under Sombra's influence until he was defeated once again.
"If Raven and Sombra are one in the same, like you say, and he's talked to you via dreams, he's been released once again."
"Then why hasn't he attacked yet?" Rainbow Dash asked.
"He's still very weak," Celestia said, "Not to mention that the Crystal Heart will keep him at bay for a while. But he will regain strength. He's trying to use your uncertainty to gain power."
"Me?" Clarity asked.
"So how is Som- I mean, Raven, feeding on Clarity's uncertainty?" Rarity asked.
"I don't know," Celestia answered.
"I might," Clarity said, "It has to deal with the Crystal Heart.
"As you all know, the Crystal Heart is powered by the light and love of the Crystal Ponies. The queen, however, played a major role in channeling the energy to the heart. He's trying to diminish the light within me to gain power. And I think that it's working."
"We have to see Princess Cadance," Rainbow Dash said, "She may have an idea for what to do!"
"We already spoke with her," Luna said, "She's expecting us."
"They won't want to see me," Clarity said.
"Why not?" Pinkie Pie said, "It's always great to see a friend after a long time!"
"They may not consider her a friend anymore," Play said, "The librarian I spoke with acted like Clarity abandoned the kingdom. They may not take her return lightly."
"Don't worry," Twilight said, "We all have your back."
"Thank you, Twilight," Clarity said.
