Is Mother Pyrexia a Saint?

Mother Pyrexia is a title, not the name of the character. She may be someone who was sick or infected with something and transformed into a different creature. We're miners, mostly here in sultas, and we were used to things found underground. But we took to our heels and came back with torches. Is a line that rings a lot more louder than I can read. And not only the use of things that run around, but they know that the solution to it is to have a lot of light.
