Say that on a fantasy world the light from the sun disappeared, either blocked out by a powerful spell or the sun just died out (or something else) and covered the world in darkness. A large group of powerful mages cast a spell to bring light (and hope) back to the planet (though the sacrified themselves in the prossess) and this spell became their light source, feeding of the excess mana of the world. If this was told in a fantasy story, would you be willing to believe it? This is just a random idea that came to mind when I was thinking about the map for my world. The other day, a thought of an equator line came to mind, just got me thinking, do I need to worry about it with a fantasy world - the answers I got here brought about this idea, but I'm not to sure if readers would be willing to believe it. I haven't worked anythng out about it just, but this is just the basic idea! Your thoughts would be really welcome! Thanks in advance!
