On a normal day,there a spark of sliver and red in the middle of the ocean.
"Where did she float from? Wait that shackle is she connected to the tower of heaven!"
After dragging the red hair girl into her small dimensional space .for the whole day Solar continues to fly and search for some trace of the tower but to no avail.
"this search is not going anywhere ,I should go check on the girl"
With a swipe of her hand she opens a hole in the air and go through it without any sound .
The space is around 10m3 there are a queen sized bed, a table, a closet and a bathroom and more.she walk to eaza and check her condition.after that she goes to make some Grilled meat for both of them.

"Miss may i ask are the ones who brought me here and who are you?"
Solar walk out of the kitchen and answer

The two of them eat and rest for a while they begin to talk about their situation.
"So your friend is locking up the tower of heaven and by the way that you described him,I have a feeling that he is being possessed by some kind of evil entity "
"Yes"
"So do you have any idea or any where that you can go?"
"Do you know where the fairy tail guild is "
"I think I'm going to go and join fairy tail. The guild that grandpa belongs to "
"Well erza i can take you there though unfortunately I never been to fairy tail so I can't just teleport there, we'll have to go to the towns by teleport and go to the guild the normal way "
"Thank you again for helping me and you can teleport may i ask what is your magic if you don't mind "
"OH No you don't need to worry I used space magic "
"You should go to sleep now erza it getting late and we will have to go to fairy tail tomorrow "
Solar pov
As i get on the bed and sleep near erza I suddenly feel that her magic energy is very familiar to some I know.(now that I think about it she looks so much like irene is she connected to her in some way,if so this could be a chance for me to repay irene for her help and guide . I guess I should just join fairy tail with to look after her and I could still investigate zeref ,the only difference is that I will be in a guild)
"It is decided then!, I join fairy tail "
"Hmm...? Join fairy ?really"
"Yes I decided to join with you sorry I was talking out loud "
After talking with erza a bit more we all go to sleep .
