Human: Produce a detailed written description of a depressing scene inside a medieval library with a tapestry, books, and shelving. Assistant: 
Partly cowled by a massive maroon tapestry, a solitary window provides a limited and distorted view of the world outside. Boards crisscross the window, further minimizing its usefulness and blocking up the larger of the vacant panes the way a vagabond might wear an eyepatch. Rows of dilapidated shelving cover most of the other walls, the soggy remains of paper a sign that many books have been lost forever.
