Welcome to tormentia! Have a good read.

but before you start to read let me explain the “concept” of corridors. Every corridor is a separate dimension that is infinitely spaced in between each other, each corridor can range from having an entire universe acting as a corridor or just making the corridor the diameter of a planet. The people who “owns” these corridors are known as Corridor candidates or Corridor caretakers, the corridor candidates are significantly weaker than the corridor caretakers. 

That is enough information for now so Have  fun!
