Greetings, I am currently attempting to construct a somewhat authentic word based magic system for a potential (medieval high fantasy) writing setting and am quite happy with what I have achieved thus far. Here are some articles from my MediaWiki which provide necessary information: Magic and Magicka However, I struggle to find a satisfying solution to the creation of magicka, as I don't want it to just "plop" into existence. Some of my thoughts were: A crystal that converts heat energy into magicka. Problems: How? Potential earth-cooling. Several things which convert chemical energy, light, sound, wind or kinetic energy into magicka. These ideas seem to be the most promising of solutions, though for the second point I am not sure what would transform the listed energies. Some sort of magical tree seems most likely for chemical energy and light. Then I am also worried about the finiteness of these as an energy source, as magic is supposed to be god-given, but it is something I concider.
