Yugi looked up and said "he can't find them,..he needs a way to locate them in there" 

As Yami was pulled away Serena took off after him, both vanishing in the dark. Serena ran hard, looking around as she did. "Yami! Yami where are you?" A voice said somewhere in the dark "look inside yourself...you must remember who you are..." Serena looked around, her pendent glowing brightly. She stopped then closed her eyes. "Focus...just breath..." A laugh was heard and she opened her eyes to see a young Yami standing there, wearing white robes of a prince. He waved and then ran away, Serena running after him. After a few minutes Serena saw the real Yami hanging in the air, a pair of red eyes floating above him. Serena stopped running, panting as she called "Yami! Hang on I'm coming!" 

Her pendent glowed brighter then the same voice said "call your birthright...your king needs you..." Serena looked around then she held out her hand and she said words she had never heard before left her lips, sounding old and powerful. There was a flash of golden light and a gold staff appeared in her hand, glowing same as the pendent. 

She grabbed it and ran towards Yami, her eyes gold now. She faced the eyes and said "face me, demon of the shadows...my king is under my protection..."
