The title granted to a crawler who survives a floor while infected with vampirism makes the curse permanent.
Miriam Dom gains the Princess of Hell title after descending to the fifth floor while infected. She explains that any crawler who completes a floor under the curse receives a corresponding hellish title and can no longer be cured through the short-term progenitor rule.
Miriam's recent descendants have not yet crossed that threshold, so her death at dawn can still cure the crawlers, dinosaurs, and animals infected from her line.
A system-granted title associated with permanent vampiric status.
The title defines the deadline after which temporary fifth-floor vampirism becomes permanent.
