Clerics of Janiosen are neutral not out of apathy or an inability to decide, but as an intentional balance between extremes they find equally dangerous. Their mythology tells of a battle of the planes which threatened to tear the material world apart in its fervor. In a rare intervention, the greater gods took the two opposing dieties and forced them into a pocket dimension that could only be opened when one being remained. They believed that either the pair would war for eternity without harming any more bystanders, or one would emerge vitorious but too weakened to do any more damage. Instead, after millenia had passed, the dimension was exited by a single being - the two faced god who had melded their seemingly immutable differences into a balance. This new being sought out other polarized opposites to understand and reconcile until it was truely Janiosen.
[there will likely be a PrC for followers of this diety]
