The Navigator: Hades OC

Wanted to try doing something in the Hades game art style. Great way to challenge myself, and practice designing from scratch! 
I figured since Mylo originally is great with maps, he would be some sort of Navigation/Steering souls type of being. Maybe a demi-god? His Staff is inspired off the Antikythera mechanism. His book I figure would be each souls destination/fate. I really leaned into astronomy details/compasses. As well as his little underworld locator sphere that he's able to control.
