My main, a Breton Druid, is a generally good but neutral character. He protects the balance and beauty of nature while reviling Undead and necromantic ways. With that said I'd have to say he would pay homage to Yffre, Kynareth, Dibella and Hircine as his personal pantheon. Yffre and Kynareth being the most nature oriented Aedra (Yffre might not be considered Aedra? Not sure), and Hircine being the diety of the wild predatory nature of the land. I say Dibella too cause there is beauty and a certain type of innocence in nature and most people and that is what my character seeks to protect.
