Background
In "Not Long Before the End", the Warlock, a very powerful sorcerer at least 200 years old, observes that when he stays in one place too long, his powers dwindle, and they return only when he leaves that place. Experimentation leads him to create an apparatus consisting of a metal disc enchanted to spin perpetually. The enchantment eventually consumes all of the mana in the vicinity, which causes a localized failure in all magic. The Warlock realizes that magic is fueled by a non-renewable resource, which would cause great concern among the magicians.
In The Magic Goes Away, the widespread diminishing of magical power triggers a quest on the part of the most powerful of the magicians of the time to harness a new source of magic, the Moon.
In The Magic May Return, it is discovered that mana was originally carried to Earth and the other bodies of the Solar System on the solar wind, which replenishes mana slowly over time. At some point, a god created an invisible shield between Earth and Sun that intercepted the solar mana and caused the eventual decline of magic on Earth.
