Can't we continue with the plot before graf did the magus games? Where everyone enjoye school life and killing each other.
Teachers can be more active.
Classes can be gone to and collabs can be created.
People can make their own plots and do their own things. Just as nature intended it.
Realistically if Graf has only been gone a few days irs not cause for meltdown. Give it a week. Sometimes shit happens mang. Best you can do is keep the ship sailing while the captains in their quarters.
