I am pretty sure Ivan has been working solo the whole time, he had no idea what Lumen Histore is. He wanted it despite not knowing what it is, and despises Fairy Tail in general. But at the same time, Obra did have a minion in which was with Zeref so there could be some connection. Either it's because Zeref knows he's closed to Fairy Tail so he put some sort of "eye" to spy on Raven Tail --> Fairy Tail.
