TEXT: Notes and Errata for KEO4-05 
   
  • There is a great deal of confusion about Lady Hannah’s age. In the Linth Primer, she 
  is supposedly born in 576 CY. This was a typo. She was born in 586 CY. At the time 
  this adventure takes place, Hannah is eight years old, not sixteen as mentioned in the 
  module. 
   
  • The Nethernight cannot be taken, controlled or otherwise affected by the PCs. If 
  seized by a PC, it appears around the neck of Lucius Linth (or Hannah, if he is dead). 
  Furthermore, the Nethernight’s corrupting influence causes everyone except Averyn 
  Linth to generate a moderate aura of evil for purposes of detect magic spell. Only 
  Averyn will detect as good for the detect good spell.
