Among the ranks of the white wastes and the endless seas of Plincy roam the hovercraft of the infamous religious mercenaries, Isbjörnarna. The side of each craft is emblazoned with the logo of a striking polar bear: claws extended and fangs bared.
There are three things, each sacred and bearded: Moon, Monks, and Moss. All connected. Tied together by the Monks of the Bearded Moon, an old order of healers, mystics, bearers of the secret knowledge, and inheritors of the Bearded Moon's gifts. Theirs is a sect full of mystery and bound by ritual.

You find a patch of edible funghi. They taste well and all, no ill effects. UNLESS you consume some beverage, even 3 (three) days after eating it. Then you become really sick with pains, vomiting, all the fancy stuff. As a gift or good meal, it could be a cruel joke or to make sure the heroes spend their time focused on the mission. And the fine soup you had in the inn yesterday could have some in.
(Inspired through a real-world fungus. Was really used to cure alcoholism.)
