Magic is the power of the heart, it is based off feelings. Psi is the power of the mind, it comes from imagination. Magi gathered to stop the corruption of the psions, and the psions came together to end the destructive forces of the magi and a great war ensued. This war lasted many years and spanned across many worlds. Thankfully Equestria has always been safe from this conflict, but now a young psion named Hotshot has arrived in this peaceful land full of spell casters.
