I was in Mac Anu when the Matinence Break was being done, and when CC was updating the building textures and such I went to the gate to see if I could warp anywhere, and when I examined it I was warped into a weird field. It was no type of field which I have seen before and when I moved my character I heard a weird sound, I belive the tone was "A in C Major", but thats just what it sounded like to me. Then a weird character appeared in front of me, it was a girl I think she was pale with dark yellow eyes and she wore a white dress. she grabbed my arm and the tone intensified greatly to the point it hurt my ears. I tried logging out but it wouldnt work. Out of know where my sword started glowing and my weapon changed into one I havent seen since "The World"'s beta, Fragment and the sword was never obtainable in the game it was just weilded by a statue in the main root town.
After the the AI just dissapeared right in front of my eyes, no it wasnt a transition effect her figure literally just dissapeared and then I was back in front of the gate and the matinence break was over.
Im not sure if it was a glitch and maybe that was an event that wasnt released yet or maybe it was a hack.... or maybe it was her...
