That's cool. Since 3e came out I wished they made a divine caster who casted her spells spontaneously. Basically, as you mentioned, a divine answer to the Sorcerer. Not sure if that's how you have Mystics set up, but they sound cool. Almost like psionicists.
In a way, that's kind of how I view mystics... Krynn's answer to psionics, since Krynn doesn't allow for psionicists (by the core rules, anyways...though there's always home-tweaked!).
Although mysticism was only truly "discovered" in the Fifth Age, while sorcery was "rediscovered," it is certainly possible that some few people throughout history somehow tapped into that inner reserve of power, but without any formal training, were never really able to develop it.
If you look at some of the design notes and original information about the Silvanesti elves, you discover that they once possessed
telepathy, but it had faded over the years until only some of House Royal possessed the power. Given the Silvanesti embracement of the Orders of High Sorcery, over time, anything that wasn't High Sorcery was probably ignored until it faded away.
During the turbulent times of the Fifth Age, however, the raw need for something to replace the "lost" (however temporarily) magic allowed for mysticism to once more begin flourishing.
