Your pigeons, however, follow your previous trail, and are able to figure out that the Base seems to be underneath the church itself. Behind the church they can see a doorway down to the catacombs, with many otherworldly creatures exiting and an ominous blue glow coming from the catacombs itself. However, upon noticing this, they are attacked by some of the creatures themselves! If they try to escape they could have a chance at survival, otherwise they could press on and try to gather what info they can, but likely perishing. Either way survival is not guaranteed at this point. (The otherworldly creatures do have the capacity to fly themselves)
