Goldgrass

Goldgrass is a herb which has been used for hundreds of years by the Church of the True Lord as incense during rituals and masses.

History
A confessor decided that instead of inhaling small doses of the smoke from the incense he made a potent batch and placed within a pipe. The result was a high which calmed him and made him feel funny.

He started growing and harvesting this at his mansion and bought slaves from Rhûne to work his fields, he eventually quit being a confessor and started an underground drug imperium.
