"Ah...Well you are partially correct. Twilight is the neutral ground of light and dark. Whether this be evil or good. BUT. The power of light, as well as the power of darkness struggle to be effective in such a place. As they have nothing to draw from. The Fierce deity is a wielder of light, he is significantly weaker in twilight, but has a gem Allowing him to still be effective. Where as Shadow, a wielder of...well shadow and darkness. Could not use her powers in the dusk of twilight." Think of it like...math. You have negatives and positives. Then, you have zero. Zero is neither a negative nor positive. Therefore a positive number cannot be zero, neither can a negative."
