Just because a deity has a preference doesn't mean they can't do something outside of that realm. Take a look at Boreas, god of the wild northern winds. Boreas is pretty much well known for his power of the cold and wild northern winds, and to a lesser extent, all winds. However, his power extends well beyond wind. People come to Boreas for a lot more than weather predictions and relief from the tempestuous winds. They come for advice, revenge, and solace; they seek Boreas when in despair, anger and joy. For those who follow Boreas, they come to the deity for everything. So Boreas knows about meditation, magic, growing things, undead things, portals to other worlds, information, criminal dealings and so on. So, a follower of Boreas, needing guidance on arcane matters would still call on Boreas to answer it. Boreas, in turn, may ignore or answer the question or refer them to another, depending on the whim of the god. Boreas may not be the best (among the gods, at least) in the particular area, but he will know/be able to do it. Even in the polytheistic mess that is divine spectrum of Arduin, this case stands firm. Let me provide another example. Amarydion, the earth goddess, doesn't provide prayers to her followers. She universally requires them to employ rituals and rites. She does, however, have a vast knowledge of prayers, and could easily answer questions about them. Just as should could about the moons, demons, or anything else for that matter. Just as Boreas could. Her focus, however, is NOT those things but instead the green, growing things and the land that brings forth the life which everything else depends on.
My point in providing these examples is to expand your mind and concept of the deities. They are not simplistic beings, especially in gaming. Arduin embraces a most complex view of deities and their use in game play. Boreas and Amarydion, my two examples, both have their focuses, strengths and weaknesses. They have goals, needs, and wants, and opposing factors that force them to make choices, just like a character does. So, Amarydion might allow the land to be despoiled, for example, to spur forward an act of greater import to her somewhere or somewhen else. Amarydion may allow the Faerie to take back land, taking dominion over it even though she's opposed to them on a general level. It depends on the goddess's goals, needs, and opposition. Boreas might help Lyrra against her son Megalon, even though he's not aligned with either – especially if it aligned with his goals or needs at the moment. That's why its important to not define them in simplistic terms. Saying Amarydion would never countenance despoiling of the lands is false: she would let it happen to make a greater goal occur, howsoever defined. In fact, in CY 303, she pretty much did exactly that, when she let a large part of the Oakendark Forest burn though the actions of her followers. It ravaged the northwest corner of the forest, nearly destroying it. At the same time it destroyed a contingent of Undgulon Faerie from the Shadow Court, drove out a nest of Trivern, spread ash to feed the soil for a massive area around it, brought back one of her artifacts that had been lost since the Nexus Wars began, and inspired the people of northern Falohyr even deeper into her faith of her.
