As our army kept advancing through the ground floor of G'Henna's castle, we reached an area closer to the center where our visibility got even worse, not because it was darker but because there were massive coralline walls blocking our path.
The walls seemed to have grown naturally and were arranged in a strange pattern that almost resembled a labyrinth.
We could sense demonic energy flowing from within the coral labyrinth, so it was clear that there were devils somewhere around those walls.
To make our transversal of the area a bit easier, we decided to send smaller groups of soldiers so that they could explore every nook and cranny. Even though some of the pathways in the area were pretty wide, sending a thousand soldiers or more through it could easily work against us.
