As the last paragraph began insinuating, alignment and relation are critical in praying to gods. Each god has it's own alignment, and their relationship with you will be based on how lawful/chaotic you are yourself. You can usually pray safely with other gods of similar alignment. Obviously, the [[Valpurus|Kings of Gods]] and the [[Mortifer|Destroyer of Worlds]] will be pissed for having affairs with the other, but even if gods are the same alignment, they can become displeased with you. It is best to limit gods to only 2-3 at most 5 levels away from each other (for example L++ to LN+,L- to NC+ [a common situation amongst veterans], or C+ N- to C--) to ensure positive relations with all of them, knowing that more is possible but risky. By positive relations, or a god's happiness, ranging from being 'A champion of the cause!' to extremely angry, dictate their rewards/punishments, the latter of which can be quite severe. Praying to a happy god will increase not only your relationship with them, but also closely aligned gods. As is such, this allows you to slowly change your alignment over time, shifting from lawful to chaotic and vice verse.
