After going a bit deeper into the undeath terrain with Samuel, Richard, Bert, Garrick, and Bobby in command, the team was in the clear most of the time, as Bert reported all the abnormalities he sensed without veiling them in a gag.
They had yet to encounter any undead, as except for the 16 in the beginning, none could be felt or seen. Of course, they didn't even know if those 16 undead were killed or not.
The team, which had been alerted about the poison in the atmosphere, was moving cautiously wearing strange mechanical, triangles-filled, abstract art-patterned black masks, which reduced the poison in the air inhaled. Which meant that they didn't have a perfect way to defend themselves against poison, but since they had healers, they didn't worry about it too much, though it was only at the beginning when they didn't know the effects of the poison.
