The shadows turned to be long and thin as they continued to walk between the pillars, "Death is the easiest way to tap into the forbidden magic. Easiest as well as powerful, it is why there are human sacrifices," explained Sister Jera before stopping right before the stairs appeared.

The wall that looked like a wall wasn't one but a mirror image like the other walls making one not know that there was a secret passage which one could never find.
