Ok this could be really stupid but just another point of view.
As his name has Dust in it how about going down the route of names and themes from Phillip Pullman's 'His dark Materials' trilogy.
northern lights
amber spyglass
pantelaimon (Lyra's daemon)
Cittagazze (the town in the subtle knife)
Aurora
Lord Asriel (lol :-) )
Golden compass
As I say probably stupid and not much to do with lust.
