Total Darkness
A Simple Mod that changes a couple of things:
1st, Similar to my Other Light Mod "Darkness and Light" it reduces the overall brightness of nightfall.
2nd, it changes the sunrise and sunset hours to be more "Earth-like" at 6 AM and 6 PM (Original Vanilla says between 5 AM and 11 PM is daylight)
Finally it reduces overall brightness by just a tad, which renders night even darker than "Darkness and Light".
This is a global mod so load it towards the bottom if you can help it. (So that more wide-reaching mods can take priority)
