Kubera is lord of all riches in the ground, a dwarfish like god who lives in the himalayas in a lavish castle on one of the peaks, He is defender of the north and leader of the Yaksas a dualistic spirit form acting as benevolent nature fairies in some cases and also nasty people eating underground orgres.
I also us Kubera Jones the Lord of wealth as my blogging avatar for the silver page. Only one reader has ever caught the reference, Kubera is a minor god more popular in nepal and area than India proper.
Another I use is Jim Kalkin ( Kalkin being the last and final avatar of vishnu that will arise in the last days of earth, the hindu equivalent of the second coming)
