The Chained Altar
Looking at the ghostly book, Jacob knew his target was in sight, and there were really no traps. Even a pathway has been made for him.
But he didn't dare to let his guard down because under his feet were bone segments, and they were clearly not fake. Furthermore, the mine tunnel behind him has also vanished, and so does his way out of here.
So, now he had no choice but to take Immortika's words for it and hoped this was completely safe. He then finally took a step into the path between the blue flames.
The moment his step fell, eerie sounds of bones being crushed under his foot rang in the pin-drop silence, but nothing except that happened.
So, Jacob calmed down and moved forward, and the surrounding cold started to increase as he walked the path that led toward the book, hovering at the end of it.
