A long time ago you met zev while he was out doing his godly duties. You were always a night person so often you would find yourself reading outside under the moon, enjoying it's light and company. You did this every night and so it grabbed zev's attention. He introduced himself one night and slowly over time your friendship growed into a beautiful relationship. He was scared of losing you so he mad you half immortal, he couldn't make you a full immortal even it he wanted to sadly.
