The Archives of Time
Aeons before he was recognized as the most dangerous magician alive—an ageless master of the arcane arts—the Invoker endured scholastic life as the adolescent star pupil at an ancient wizard's academy. Even as he excelled at every task set before him, and basked in the praise such aptitude afforded, the young Invoker dreamt of a future in which he answered to no one but himself, where he might finally be free to wield his growing powers however he saw fit.
Now, harnessing dangerous magics purloined from his headmaster's secret archives, young Carl has discovered the means to journey forward into his own timeline. Eager to insert himself prematurely into the moment of his greatest triumph, Carl is determined to prove to the world that aged or not, the illustrious arts of the Invoker can be bested by no one.
While he's confident that he's bound for triumphant adventure, had he read the entire description of the spell before casting it, the young magus would know that failure to accomplish his elder self's fated mission will result in each timeline's certain demise.
