From publisher blurb:
An invitation-only club for Chicago’s elite, the Delphine Society is nigh unrecognizable from the association started by Charles Avingdon Villieport in 1818. Ostensibly dedicated to preserving the business interests of Chicago’s wealthiest mercantile families, the lure of spiritualism has changed the society irreparably.
She Who Rules the Sea details the Delphine Society, giving the GM everything they need to insert the organization into their Whispers in the Dark campaign:
Society history and plans for the future
Notable Members
The Dreadful Penny
Scenario Hooks
Using the Delphine Society
Gifts of Amphitrite
Statblock - Tough
For use with Whispers in the Dark, but with plenty of system agnostic details to be of use with any system set in a the Gaslight Era.
