"So, in 1785, a group of scholars - Ambrose Westcott, Kitty Mazarine, Solomon Husher - acquire the deed to the Dewulf estate, and establish 'Curia of the Isle', with Westcott becoming first Librarian of the Hush House. They establish Hush House as a haven of knowledge, a proper library. Westcott is rumoured to have died of apoplexy after a particularly hasty trample up and down the stairs to argue with visiting priests, Mazarine takes over as second Librarian, and later retires peacefully. Husher is the third, and he disappears, leaving only a resignation letter, in winter of 1838, when a heavy snow fell on the Hush House.
Curia then has some trouble with finding a new Librarian, and Fraser Strathcoyne, Treasurer of the Curia, becomes the fourth, to his annoyance. As soon as they found a suitable candidate, Strathcoyne retired, and Natalia Brulleau became fifth Librarian. After her retirement, Curia is again short on candidates, until the arrival of Williem Harries, who presented the Curia with some 'key long lost', and was appointed sixth Librarian.
The next part is a bit muddy, I couldn't quite figure out when Harries retired or where he went, but Thirza Blake is appointed seventh Librarian, and it's also not clear why. I have no idea why Curia appointed her, she was, by all accounts, quite insane, and eventually, in 1896 brought Hush House to penury.
Then the Nocturnal branch stepped in, marking another period transition. The Hush House received funding, but submitted to yearly inspections, and surrendered a portion of the Isle - mostly Crucible Tower, to be the Branch's prison. Eighth Librarian was probably also chosen in relation to that - Sir David Greene, a former Nocturnal Branch superintendent. George Collers, formerly Secretary Vigilant of the Curia, was appointed by the branch to be Governor of Cucurbit Prison, as Crucible Tower became known.
Greene eventually retires, and Brian Levinsen becomes ninth Librarian. About that time, in 1902, something called 'Ortucchio Incident' happens, and Nocturnal Branch is dissolved and reogonized into Suppression Bureau, though it doesn't affect Hush House or Cucurbit much, and Collers remains its Governor.
Brian resigns in 1914 to go volunteer as medical officer in the Great War, and has died there. Serena Blackwood becomes the tenth Librarian, but resigns early over the tensions between her and Collers. Gervinus van Lauren was eleventh, up until the fire seven years ago. And now we are here, 1936, and you are the twelfth Librarian. I should pick a new period name."
