This page lists all of the Deities of Order and a brief description of what they do.
As stated here, these deities fight for the preservation of life, which is the most pure form of order. Their followers believe that the Universe needs order, and without it, will fade into a bleak and drab nothingness. While some of these deities may not be considered "good" traditionally, their goals overlap with those of protecting and proliferating order in the world and less about personal gain and destruction of it. A lot of these deities are prohibited from being worshiped in many of the kingdoms across Gaia, as some rulers think that some deities are more dangerous than others; however, any Deity of Chaos is strictly forbidden in most civilized kingdoms.
As stated here, these gods are in constant conflict with the Deities of Chaos and subsequently their followers too.
