Novice nun

Geralt first meets the Novice nun at St. Lebioda's Hospital. She tells him about the goddess Melitele and a bit about her faith. Later in Act II, if Geralt speaks with her again, he can ask a sort of cryptic question to which he gets an equally cryptic reply but it does not seem to impact gameplay in any way. Finally, in Act V, he finds her in the Safe House, along with Vaska, Vivaldi, the Elder Druid, the resolute girl and Vetala.
