Anyway, I've been doing a bit of searching at The Imperial Library for information regarding Blackrose Prison. Notably the prison break that is mentioned in the third edition PGE, under The War With The Trees (section on Black Marsh).
More troubling is the recent prison break at the formidable Blackrose Prison. Though it has since been sealed and its weak points mended, some of the worst murderers, thieves, and political revolutionaries had already escaped into the swamps. It is believed unlikely that any of them could have survived the cruel, dangerous lands of inner Black Marsh.
I've been having quite a few ideas for a piece of fiction to write about this, however, I've not been able to find much information at all. Is there any more? Or have I actually done a thorough search?
For instance, does anyone know when the prison break occured?
