Lhurdas

Lhurdas, also known as "the yellow death" or "Beltyn's Last Drink", was an ingested poison that was usually mixed with wine.

Description
Lhurdas itself tasted like a dry, white-grape wine. As a poison, that was why it was most often mixed with white wine.

Effects
Lhurdas was effective against those of elf, human, or orc heritage. Ingesting it caused nausea, convulsions, and severe cramping as it literally ate away at the internal organs. If one survived the initial damage, then they seemed to be immune to its damaging effects for several days thereafter.

History
Lhurdas was one of sixteen formulas for poisons recorded in the book known as The Nathlum. It was thought that the formulas were originally written down by the mage Lethchauntos the Black, during his time spent with an orc tribe. Some of these same formulas were copied from the book by the mage Phrandjas of Port Llast and sold to local alchemists.
