Is Igneel really dead? In Fairy Tail, Igneel has been missing for 7 years, so I'm guessing he's dead but I don't know!

Is Igneel dead?
These are heavy spoilers, so read at your own discretion:


  Igneel and the other dragons took part in the 400-year plan in order to save themselves from the deterioration of their souls caused by Acnologia. Through theis plan, the dragons were sealed inside their children, and then they were sent 400 years into the future into a world that was teeming with Ethernano which allowed their souls to heal while inside their children. Natsu and the other dragon slayers were never aware that they had been sent into the future nor that the dragons had been sealed inside them.
