Actor
Like every persona Lavi had been, Lavi was, to a degree, real. Each time a new personality was created that was who the bookman apprentice became. He loved his job. Like the greatest actors, he became immersed in the roles.
So he became Lavi. Happy, carefree Lavi. The clumsy apprentice bookman. That was who Lavi was.
When he talked to his friends, that was what he thought of them as. Friends. Without hesitating, he would risk his life, die to save them. But Bookman was always there, reminding him where he was, who he wasn't.
The junior bookman was the best actor ever. His masks had no holes, no flaws. He became so absorbed in each role, it became so easy for everyone, including himself, to forget that was what each was. A role. A fake, just like a character in a play.
Lavi always got a thrill creating a new personality. He would think over it for days. He would think of the flaws, qualities, how he grew up. He would think about it until in his mind that person was real. Like an old friend.
He enjoyed his time at the order. It was fun. Great fun. But that life wasn't really his. It was Lavi's.
As Lavi, he had friends, emotions... dreams.
But in the end, Lavi was just a name. And when they moved on, that was the first thing he forgot.
