From the Books: "Another bear of a man lounged next to Andrija, but where Andrija was the bear of fury and rage, this man was the seated bear with a fish in his mouth and a honeycomb in each paw. He was the kind of bear that would only attack if he had eaten old apples that fermented in his stomach. Otherwise, he would merely look for tastier and easier prey. He casually introduced himself as Zacharia. His tunic was barely tinted yellow, as though the dyer had introduced it to saffron but separated them before they could get to know each other well. It was not linen, wool, or silk, so I guessed it was cotton, but I did not care enough to investigate more thoroughly. There was an aura of danger about him that led me to think he sought out those fermented apples whenever he could." - ALMD, p. 100
