Tell this guy to act really jaded about the world, government of the "shortlives" and have open disgust of the half races (including outright rudeness to half-orcs, commenting on "how in the nine hells did your parents meet? and how can I go back in time to kill them") make the elf show superiority over everyone, including the liches "your existance is a mockery to life itself. how can you show such disregard for the wheel of life, death and rebirth. you are causing the world harm. what do you think you can acheive in your fleshless body")

then try and get the elf to create some half drow and a fascination with spiders.
