From Tapestries MUCK
"Called 'Koki' (Zoom), it heightens sex drive by leaps and bounds, as well as energy levels, and reduces sanity to an all-time low, even for Lutrai. The drink is laced with a narcotic nectar found in certain carnivorous plants, and composed primarily of fermented honey, sweet herbs, and milk. It is also frequently boosted by the magic of the tribal healer to promote fertility and check any contagions. A Lutrai on Koki will be nearly impossible to restrain for hours, and will always try to remain in motion."
Koki is very popular in its use during Kitseve.
