Under Illefarn is a 1st-edition Advanced Dungeons & Dragons adventure that was set in the Forgotten Realms.

The adventure is a scenario designed for beginning players in the Forgotten Realms setting. The player characters are residents of the town of Daggerford, and are therefore automatically members of the town militia and thus required to deal with local perils, such as fighting lizardmen raiders, rescuing a kidnapped noblewoman, and guarding a caravan. The module describes Daggerford and its personalities, as well as the nearby dwarf and orc lairs of Illefarn.[4]

A curse is on the land.

Daggerford is fairly quiet for a frontier town. Sure, lizard men raid the local baron's holding now and then, orcs sneak out of the Misty Forest to raid caravans on the Trade Way, and Lady Bronwyn has a few suitors who are a touch too passionate, but there's nothing going on that a member of the renowned Daggerford militia can't handle.

Except that the Shining River has turned green, and cattle are dying. Except that the Elf King of Laughing Hollow, a place where no human dares to go without fearing for his life, is asking the militia for help. Except that strange substances are oozing from the fissures caused by a recent earthquake. Except that the earthquake also has opened an entrance in the cliffs around Laughing Hollow that might lead to the fabled dwarf mines of Illefarn.

Suddenly, being a militiaman isn't quite as easy as it used to be...
