Lucy's power

Training finished

I heard lavender try to stifl a giggle and tried to hide my smile. A big purple bubble was hovering above my bed, ready to pop and cover me with water waking me up. Lavender loves playing pranks on me, but I always get her back.
Pop
The bubble burst but I quickly stuck out my hand and stopped the water in mid air. I then turned to my little exceed and started tickling her before she could escape.
"Stop, STOP!" She squealed. Her laughter slowly dying down and I pulled her in for a hug.
"Is Nova telling the truth! Are we really going back into the real world today!" "Yep" I gave a small smile, and tried to hide the doubt I'm my voice. "I bet you a cookie that you can't pack as quick as me!" And with that lav flew off, muttering the word cookie.
I stood up and stretched. The truth was I didn't need to pack because the only precious thing to me are in the celestial world and all my clothes are in my storage. The soft carpet gave a soft padding noise as I walk over to the shower. I need to change my appearance, enough so they don't recognise me, but not enough so they faintly remember me.
I grow my hair to the back of my knees and keep it the opal colour it is, and change my eye to a blood red. I make myself a bit shorter,  but apart from that I kept it. I took a shower with my usal strawberry shampoo, then changed into leggings, combat boots and a black shirt that had 'true friends stab you in the front'
written on it.
I step out and collide into Lavy, who had a big smirk on her face.
"Oh my gosh! How can you be so quick" I say in a slightly sarcastic tone "I guess I owe you a cookie". I use my summoning magic to get her a cookie the pat her head.
"It's nearly time to leave, ok?". All she does is nodd, due to the cookie crammed in her mouth.
We head downstairs and see Nova has the portal ready for us.
For all the time I've known her she hasn't changed a bit.
We hugged and as we drew apart I felt something in my hand.
"For you". My dragon sister as we call each other, tapped my hand and a small necklace and ring shone.
The necklace was a tiny key on the end of the string which I instantly saw as hers. The ring was a diamond dragon with black eyes, which I could see would look like it had coiled itself around my finger.
"The necklace is too summon me if anything happens, and the ring is to contain you magical energy. Please be careful" She pushed me away and gave a last hug to lavender before she started to wave us off.
Lavender sat on my shoulder,  nearly hidden in my hair, and we walked through the portal...
