GURPS Fantasy: The World of Trifourian
Bloulug Blossom grows in the alpine meadows in the Northern mountains of what is now the Kingdom of Fumeguard. It appears to be a midnight blue flower whose petals curl inwards around a single green thorn. When crushed into a powder, Bloulug Blossom is a highly addictive narcotic. It was at one time used in the religion of the mountains ancient Dwarf inhabitants. With the arrival of the Kingdom of Fumeguard and the enslavement of the Dwarven people, the secret of the blossom’s properties was discovered by humans who now use the plant as a means of maintaining control over the enslaved Dwarf population.
