Quirm is also famous for its (blue-veined) cheese. Quirmian cuisine is generally characterized by containing avec (French for "with"). Quirm is a duchy, ruled by the Rodley family. Members of this family seen in the books include Lord Rodley, an upper-class twit in Mort, and Brenda Rodley, the swamp dragon-breeding dowager duchess in Guards! Guards!. In Sourcery, Quirm was destroyed by wizards during a magical war, but was presumably restored by Coin when he put everything back as it was before the war. The Quirm College for Young Ladies is an educational institution located in Quirm. In the books, Susan Sto Helit, Lady Sybil Ramkin and Miss Perspicacia Tick were educated there. The school's headmistress and founder is Miss Eulalie Butts (possibly a reference to Frances Buss). It is explained in Soul Music that few of the Discworld's higher-class schools (such as the Ankh-Morpork Assassins' Guild School) see fit to admit female students (although the Assassins have since changed this policy), so Miss Butts founded the College "on the astonishing principle that, since gels had nothing much to do until someone married them, they might as well occupy the time with learning things." The school resembles a traditional English independent girls' school, with an academic curriculum and a heavy emphasis on respectable and decent behaviour. The school's strong emphasis on decency reportedly makes it rather difficult to teach certain areas of Biology; students come out of that class "with the vague idea that they were supposed to marry a rabbit" (Soul Music). Students at the school do not seem to be preparing for any particular profession. As the known universities on the Disc are solely for wizards (who must be male – see Unseen University), and most other higher education institutions on the Disc do not admit females, there is no clear lifelong aim for the school's alumnae. Susan Sto Helit describes it as "an education in, well, education" (Hogfather). It appears that those students who do not marry upon leaving school generally go into the teaching profession themselves, or become governesses. Staff include Miss Butts, the Headmistress; Miss Delcross, the Biology mistress; and "Iron Lily", the gym mistress. Sto Lat Sto Lat, ruled by Queen Kelirehenna, is located about from Ankh-Morpork. According to the books, Sto Lat is a sizable walled town in the Sto Plains, although eclipsed enormously both in size and influence by the neighbouring city of
