Xthylistic curd (pronounced "zy-lihss-tik") is a script ingredient made from dried marrow and powder from ground bones combined with fluid from the glandular ducts of specific sea monsters (which kind is not specified). It is a standard ingredient in Cathar's Treacle. Lard of Nmis may be substituted in its place, primarily for its euphoria-inducing effects.
Avarïce mentioned the use Lard of Nmis in place of xthylistic curd to Rossamünd Bookchild along with some other possible substitutions. However he recognised all of them as being addictive and corrupting.
