Rabe thought back to the beginning of his second year at the Academy. Intermediate Runic Application was one of the classes he had been most excited to take, and if the syllabus was any indication it would have been a fascinating and informative class indeed, but two weeks in the letter came, and Rabe returned home. He flipped through the textbook every now and again, during nights he couldn't sleep, but as firm as his grasp of the theory had become over those many nights, it was no substitute for actual practice.
Which was why he, a bona fide caster, was now staring up at a Water Rune, lungs burning and wondering what to do next.
Well... here goes nothing.
