About me(an Alien)

so my name is Echo. i don't know who i really am. my name was given to me by some man i don't know from a place called "Doll House". then Elina found me and and introduced me to the others. Luna and Techna. they too where from a "Doll House". Elina taught me where i am really from a Alien planet. like Luna and Techna. Then everything changed when Luna discoverd weird purple Tattoos on her skin, at the same time Techna and i did too. and we have special powers. we use them for the good of your planet Earth. hoping to find a way home.
