Arcadios is just using Yukino because she has two gold keys (libra and pisces) and the key to the 13th zodiac. Arcadios tries to fool FT so that he can take the 10 zodiac gold keys from Lucy so the Eclipse Plan can take place. I think it's a gateway to another world. The dragons may return soon, Acnologia and Zeref.
