While Berengar was away at war, one man was in Kufstein working exceptionally hard to cover for the King's absence; this man was Chancellor Otto von Graz. After the debacle with Liutbert, Berengar had selected someone else to act as Chancellor.
However, this man had utterly failed to live up to the task. Thus when Berengar promoted his Uncle and soon-to-be father-in-law to Marquess, he also gave him the position of Chancellor, which in Berengar's Kingdom was equivalent to the Vice President.
Otto had been working at home in Graz during his tenure as Chancellor until now; after all, there was not much work that needed to be done in such a position. Now that Berengar was off at war, it was the Chancellor's job to rule in his stead.
