In my campaign world, I have had a pantheon of nine deities. Originally, they were one for each alignment, but over time, the alignments have been removed (kind of) and they become patrons for portfolios. As such, I started referring to them as the "Great Wheel," in which the aspects of eight lead from one to the next, while the ninth acts as the hub of the wheel. All intelligent animals and beasts in the campaign world worship the nine, but typically with different motivations and aspects--as if they could be different religions altogether.
The All-Mother is the hub of the wheel, representing society, family, and life of the everyday. She keeps the balance, and keeps the wheel spinning. He symbols include the wheel, a tree, or a pregnant woman. She holds parts of all magic to her domain, especially anything Universal.
The Ever-Seeing Eye is the god of innovation, new ideas, and the mind. His symbol is an eye or the dawn, typically in a triangle or pyramid. He represents dawn, and is the creator before creation. Divination is his domain.
The Wild Father (sometimes the Grain Father) is the god of life, the wilds, agriculture, and abundance. He represents the morning when everything awakens and grows. His symbol is anything alive, usually a sprig of a wild plant or harvest. Conjuration is his domain.
The Ever-Vigilant Sentinel is the god of solidity, surety, and protection. His time is noon, when much is revealed, and we are at our most watchful. His symbol is stone, shield, the sun, and occasionally a lock. Abjuration is his domain.
The Beloved is the goddess of love, delight, freedom of emotion, and storms. Her time is the afternoon, as the day winds down, storms advance across the land, and celebration begins. Her symbol is a flower or anything of beauty, or a stormcloud. Transmutation is her domain.
The Nameless One is the god (goddess?) of lies, uncertainty, long shadows, and mystery. The One's time is dusk, when shadows are at their longest. The Nameless One would never be identified with any particular symbol. Illusion belongs to the Nameless One.
The Temptress is the dark twin of the Beloved. Her portfolio includes desire, certainty, captivity, and emotions that lead to servitude. Her time is the evening, when people give in to temptation. Her symbols include a black sphere, spider webs, and mushrooms. Enchantment is her domain.
The Warmonger is the god of battle, strength, and the stars. His time is midnight, when the stars lead the way for the most belligerent races. His symbols are any weapon, and the stars. Invocation is his domain, and fireballs are normally thought of as stars brought to earth.
Following War, of course, is Death. Its portfolio is the dead, the cold, and the long quiet stretch of time in the early morning before sunrise, when the world is at its quietest and coldest. Ice and anything dead are its symbols. Necromancy is its domain.
