Trapped
Much like the cathedral, the fog on the first level was thin and didn't completely block their visibility. The echoes of their footsteps spread out long before their arrival - it couldn't be helped as it was much harder to stay silent with so many of them travelling together. But there was no one around to notice which, given their location, was fortunate.
However, they were greeted with the sight of dried blood as soon as they descended, as well as countless Mutt corpses piled in a corner, as well as a few berserkers. The upper level had been cleaned since there were so many soldiers around who could go there, but in the basement the best anyone could do was pile the corpses on the side.
Naturally, that also left behind a strong stench of death and decay all around them, creating a nauseating environment. There were stairs leading further down, but they didn't need to go there, as their target was on the very first floor.
