Long ago, three eccentric dwarven scientists, shunned by their more conventional brethren, found a remote corner of the underworld in which to conduct their under- botanical experiments.

Grimtar, Vamshal, and Korgold ventured deep beneath what was Castle Whiterock, to an empty cavern with fertile ground for growing mushrooms, mosses and other under-plants, finding it a perfect cave complex to house their laboratory.

Unbeknownst to his companions, Grimtar, the leader, had a secret agenda...

This brief adventure can be run as a one-shot convention game, dropped into any campaign, or inserted as a side quest within the confines of Castle Whiterock.
