Yeah! The only thing that made me happy about this chapter is I was right about the power source and the Exceeds played a good role of defeating a main villain.

It would have been cool if the power source was a giant beating heart like what Aldarinor said which was beating then Pantherlily stabbing it with his new weapon causing Hades to weaken. Hades escapes to the woods then stumbles upon Mavis's grave, dying he regrets everything he has done asking for forgiveness then Zeref came and killed him or Zeref just watched him die then awakens.
