I did... Or, at least, I think I'm finally free. I discovered a hidden room underneath the floorboards of my bedroom, and after getting past some runes the Archmage had left behind as a trap... I met my older self who's been trapped there, who explained that this wasn't our first meeting, and that I've been repeating those five days for thousands of years... but I've forgotten everything everytime I went back.

She explained that the Philosopher's Stone, which the Archmage had been after, was responsible for the repeating time, and that to break free of it, I had to break the Stone before the bells on the fifth night finished ringing.

[Except...]

Just when I was about to do so, though, I arrived here.
