Rite of the Black DrinkEdit
(Level Three) Some nations purify themselves and prepare to speak in council by partaking of a noxious black liquid that causes them to vomit. It is thought that purging their bodies in this manner cleans them of all impurities and thus gives weight to the truthfulness of their words. Despite its black color, many nations call this the White Drink because of its reputed cleansing properties. The Uktena (and later generations) call it the Black Drink and have built a rite around the consumption of this purgative.
When consumed as part of this rite, the Black Drink not only purges as it is meant to do, ensures that all words spoken for the next hour are true and also reveals whether anyone drinking it harbors a Bane or other unclean spirit within his body. Those so afflicted will seek to escape drinking the liquid and if forced to imbibe it, will be unable to regurgitate it. Their skin mottles visibly with black patches which last for an hour.
This rite may only be performed when freshly made Black Drink is available. The drink cannot be carried along and used as a "Bane detector." The point of the rite is to make certain that all parties intend to speak truthfully and cleanly; discovering tainted spirits is an added bonus. No roll is needed to enact the rite, but a Perception + Awareness roll (difficulty 6) allows those in the ritual to notice if someone fails to drink or cannot purge the liquid.
