I missed this when it dropped, but there's an examination of St Brides done by the Assume Nothing podcast. I've not far in, but so far it is relatively unsensationalized.

Their own summary:

Ireland, 1984. St Brides School for young ladies opens its doors in the quiet fishing village of Burtonport, county Donegal -- but all is not as it seems.

The mistress and 'girls' appear to believe that they live not only in a different century, but in an entirely different world.

They are The Silver Sisterhood...

Most of the St Brides games may be found on Internet Archive. If you like that sort of thing, they are the sort of thing that you will like. 

Happy New Year!
