Discussion Fairy Tail Mystery Questions

[WoWfan]

I am starting a Thread here that talks about what massive mysteries or things that confused a few or any readers in particular, and we talk about what they are or likely suppose to be.

I will start, this link shows an image of a massive hole in Chapter 102: Walk Strong around the end of the Tower of Heaven Arc, where I thought it was the hole left when the Tower of Heaven was, can someone likely clarify that?

Spoiler: Image of Hole

Also, how long was Jellal a member of the Magic Council?

Why did we not see any Ophiuchus post edo-spirits war?
