Castle Amber
Tom Moldvay
 The player characters explore the haunted mansion of the Amber family, and encounter new monsters such as the brain collector. During their night's rest on their way to Glantri, the player characters are unexpectedly drawn into a large castle surrounded by an impenetrable, deadly mist. This is the result of a curse the wizard-noble Stephen Amber (Etienne d'Amberville) put on his treacherous relatives for murdering him. The only way to escape Castle Amber (or Château d'Amberville) is to explore the castle, putting up with the demented and at times insane members of the d'Amberville family and the other, often hostile, denizens, and open a hidden portal to the wilderness of the world of Averoigne, where the party can find the means to reach the inter-dimensional tomb in which Stephen Amber rests, in order to break the curse and return home. In this world, magic is frowned upon, and spellcasters may come to the attention of the Inquisition.
