People hallucinate after drinking a mushroom-based liquor in a fictional, all-male one of these places in a novel narrated by the fungi in its floorboards. In another novel, a former plantation owner takes his colleagues from one of these places to a waterfall picnic, where the water muffles the announcement of his own suicide. A woman in one of these places constantly slams a glass door en route to the “Good Russian table” she shares with Marusya, the crush of the protagonist’s (*) cousin. (10[1])Following a Walpurgis Night in one of these institutions, a converted Jesuit (10[1]-5[1])arrives there to debate the Italian humanist (10[1])Settembrini. In that novel, (10[1])an engineer from Hamburg spends seven years in one of these institutions located in Davos. For ten points, name this type of institution that Hans Castorp checks into in The Magic Mountain. ■END■ (10[1])
