Bando, a hard-drinking, fist-pumping warrior mage and mentor of a magic academy, went into exile after the death of an alchemist who drank a cold-magic-enhancing elixir made from the sap of a tree. As a result of their experiments, Bando's body was partially altered by a natural reaction, and his magical abilities were enhanced, but he now needed constant doses of the potion to stabilize himself and not cause harm to others.
