The double doors to the north do indeed lead to the newer doors that have not been opened, but with this smoke toxic smoke seeing anything is next to impossible. Even so, you cannot sense or see or feel those two clerics anywhere now, which is even more distressing. The smoke just filling up all of the space within this basement lair, and not going anywhere without any proper ventilation. Yune is busy coughing up a lung to the side, groping blindly for the escape ladder and getting the nine hells out of here, but that is going to take some time, as well as none of you being able to help in that regards.
