A Did You Know On Paranormal SP

If by chance you do happen to revive Guidry (Only through cheats or mods, since he cannot be revived by any other means like from a spellcaster, wishing well or even ambrosia as him and Temerance has a special trait that prevent that.) he won't be an NPC anymore or tutorial NPC. The game will generate a new Guidry which will have the same clothes, looks and traits.

So no worries about breaking your game or some rando townie replacing Guidry it's literally just the same one. :)
