This is for a new lesser deity for the system.. It could be incorporated into any setting, and works with the standard D&De rules. I don't have a picture yet, but I am working on it.  
Pyaugterav: God of the 4 elemental magics
(Pie-og-tur-avv)  
Alignment: True Neutral  
Domains: Special* Air, Earth, Water, Fire, Magic  
Typical Worshipers: Druids, Wizards * clerics may pick two non opposed elemental domains ( air/water, air/fire, earth/water, earth/fire) They then lose the ability to cast spells from their opposite domains. The benefit they receive is that they get the domain bonuses from both their elemental choices, plus the domain bonus for magic (so they have 3 domains they may choose their domain bonus spell from, instead of just 2).  
Pyaugterav is the god of elemental magic. He is also known as Pyrost the raging, Augual of life, Terros the firm, and Aviak the free. Pyaugterav travels the elemental planes, where he is worshiped by most of the inhabitants therein. Druids and wizards involved with elemental magic worship him, fearing his awesome destructive powers. Because of the chaotic nature of the elements, characters who follow him cannot be lawful in alignment. The domains he is associated with are Air, Earth, Water, Fire and Magic. His favored weapon is the staff.  
I know this god is similar to Obad-Hai, but the special conditions of his domains, and the alignment restriction makes him just different enough to warrant at least a look-see.
