Komer's gains in the battle at Marco were unprecedented. Rebry's return not only greatly enriched the strength of his Homer-Caucasus United Mage Corps but most importantly, Rebry's understanding of the Church of Light and the entire situation in the Northern Continent was unparalleled. To be precise, Rebry's role was not limited to that of a mage; more crucially, he acted as a strategical advisor capable of engaging in comprehensive discussions with Komer.
Many matters that were indescribable to Puber or Fran could be grasped by Rebry with just a subtle hint, which was most vital to Komer. Even if Rebry couldn't be considered a confidant, he was certainly a highly reliable partner. On many issues, his insights were even deeper and more thorough than Komer's own—a fact Komer himself had to admit.
