From my understanding of what I've read, Elluka comes back at least by the Merrigod portion of the novel. I can't say yet if she's back by the time Lemy's shot. But the one whom Irina knows to be "Seventh Magician" is in fact Eve Moonlit after taking Elluka's body (Elluka being MIA and Irina believing is still alive and possibly going to make a comeback).

Considering Irina knows this but still ends up addressing her Merrigod letter to "her beloved sister" after the Lemy shot scene, I presume Elluka's back by then but I can't confirm. There's a lot of stuff happening in this book.
