Your party's greatest nightmare...is the one you create.

  Bring fear to the table with Ravenloft: The Horrors Within , the ultimate horror expansion.   As Dungeon Master, you are the mastermind pulling the strings, wielding multiple genres of horror, shadowy Domains of Dread, malevolent Darklords, and grotesque monstrosities as instruments of fear in your campaign of terror.

Inside this haunted vault, your players will uncover necrotic new subclasses, haunting backgrounds, and supernatural curses. Whatever happens, only one thing is certain: this is a nightmare your party can’t wake from... and you’re in control.

This Module Includes:

• 16 Domains of Dread (featuring a new domain)
• 17 sinister Darklords with full stat blocks
• a bestiary of over 40 grotesque monstrosities
• haunting new player options
