The Dosimi Get Hit, the Humans Get Hit

The elves that we know as the hi elles to day are descendants of a very specific sect of elves. They discovered ways of recharging or reacesing magic from the time when it's lost. People still can store magic, kind of like batteries or cisterns within themselves. And in the same way, there's certain topographical, geographical, especially rocks and rock formations, but also life of every form is capable of holding small batteries of magic.
