Yes we know that, the question of "Just who or what is Obra" in the end-summary of the blog post was meant to go beyond that and look into his exact nature and allegiance.

What kind of being is he? Why did he temporarily join up with Raven Tail? Did he do anything more than scouting for Zeref? Was Ivan duped or was it a deal between him and Zeref? If it was a deal, what did Ivan get out of it? Why would Ivan even risk a deal with a person like Zeref? ect...
