Actually a real-world fungus, just heard about it. A fungus that tastes well and all, no ill effects. UNLESS you consume some beverage, even 3 (three) days after eating it. Then you become really sick, pains, vomiting, all the fancy stuff. Was really used to cure alcoholism. May be a joke or to make sure the heroes spend their time focused on the mission.
Plant that is likely to produce allergic reactions in almost everybody, even by touch. Usage: medicinal, in very exotic foods, non-lethal traps, disabling opponents (have you ever cut an onion,anyway?), spell components, etc.
A local fungus-breed explodes if hit or fallen upon. If there is any conflict between inteligent enemies,both sides are likely to use it to their advantage.
Fedolf, the notorious headsman of Iddland, is known as much for his beheadings as for his operatic arias of doom. A tower of power, standing nearly seven feet tall, and weighing in at almost four hundred pounds, Fedolf strikes fear in all onlookers, especially when he dons his executioner's hood, and goes shirtless, wielding his gigantic double-bladed pole-axe, on his way to the headsman's block. He possesses a beautiful singing voice, and will often send off his charges into the next life, while belting out baritone dirges and antiquated arias, usually involving death, destiny, and duty, in heavy doses.
