With how focused I was on finally reaching my long target; the library, I forgot about a single, small detail.
This time, I had no access token on me!
While initially, that didn't seem to be a problem, as I passed through the first set of doors that allowed me to move from the nicely furnished and finished corridor to the same, crude tunnel, the deeper I got into the mountain, I could feel how the pressure on my body was steadily increasing to the point when even making another steep seemed like a challenge!
This title was not intended this time, I promise xD
