I lost the lantern when climbing into the Vestry from the Empty Stairwell:
Unfortunately, you have to let go of the lantern, the thick copper key, and the broom in order to hang on; they tumble into the darkness below.
I didn’t think anything of it at the time, but now many turns later, I have learned that I need the lantern to navigate with the dinghy.
Do I have any option other than restoring to a very early save? Will I also need the copper key and broom later?
