From Innsmouth to Cthulhutech, a common phrase is “non-Euclidean architecture”. But what is it, and how can it be included in your games in a way that is interesting and fun?
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.
