Lazarus paused as they spoke about the book. 'Fairy tail'. That made him smile. That guild name filled him with warmth. He chuckled and spoke to Sasha. "You know. My father used to tell me as young teen, that my real parents had elder relatives that were fairy tail mages." He smiled a bit. "The blood of a Phoenix..." he looked at his left hand, "and the blood of a fairy." He looked at his right. He now spoke out loud. "You know... they wont let us take this book.... we'll have to take it by force." He sighed. 

'Lucy Heartfillia.' He shuddered a bit and his eyes widened. He had seen that name before. Of course he had, she was the infamous stellar spirit mage of Fairy tail. He chuckled, before laughing loudly so the others could hear him. "I know what book we are looking for!" In that instance, he had already had a flashback. "The book has the same colour fairy tail crest as it's author. Find the read crest... and you find the book." He grinned. He looked at the ones about to ask how he knew. He answered before they even asked. "Being brought up in the church system, and having a 'father' as a major minister, meant being dragged to the council on many occasions. The library is where I was allowed to dwell. That book is the one book father would never let me open. I believe he feared its contents would.... corrupt my heaven bound soul." He stared sinisterly  at the others before squeezing Sasha's hand. I believe the odds of us winning this thing just went up." He beamed, almost proud of his flashback.

Lazarus responded to Damian in an instance. "Heavenly magic see's through all. I can get rid of them, provided they aren't too encrypted." He grunted.
