So, this is a thread for us to describe some of the interesting sorts of magic our worlds have.
I've already descibed some of the species specific magics this world has in "Types of people". There are a lot of other sorts I didn't get into there. Another sort of magic we have is the magic of Harmony, which is available to Element Bearers. Most harmony magic requires the six Element Bearers combining our powers while acting in accordance with our Elements. There aren't known limits on what Harmony magic can do, but it's difficult to control its exact manifestation or to direct it towards specific purposes other than "fix this world-threatening catastrophe somehow". So far the current Element Bearers haven't managed to do anything with it besides that, but Harmony magic was supposedly also used to create the alicorns, who are some immensely powerful immortals.
Becoming an Element Bearer in the first place involves acting in accordance with a Virtue then invoking it to manifest that Element in the form of a jewel. There's more to it than that, but we don't know what else was necessary; possibly it needs to be done where the last jewel of that Element was destroyed or possibly that was irrelevant, for example. That jewel can then be used by the Bearer as a source of Harmony Magic.
