Mayaheine
Mayaheine is a god of Justice and Valor from Greyhawk. She's actually an ascended mortal - she came to Oerth from somewhere else some time ago, and was a paladin of Pelor, recently. Her holy symbol is a complicated mess involving her personal armaments and a few suns and runes.
Protect those who need it. For good to survive it is necessary to defend the weak and innocent. Bravery, strength of mind, and perseverance in times of hardship or danger are virtues, and adherence to the concepts of justice, fairness, and righteousness are essential. Obedience to Pelor the Sun Father is as important as devotion to the Shield Maiden. Just as Mayaheine traveled a long way to aid our world, it may be necessary for the faithful to travel far to uphold her word.
Clerics of Mayaheine build town walls and train peaceful villagers to defend themselves. Her domains are Protection, Law, Good, and War.
