Poisonous Delicacy

From: Isabelle
Description: We have to hurry because the black fog is rapidly extending its devastating reach. We need to quickly create Plasmodium. To do this, we need another specific mushroom - the Green Caesar. Look for it urgently.
Completed: I am astonished yet again by your speed. You brought the Green Caesar mushroom! These mushrooms are named after Julius Caesar, who loved them. Agrippina, wife of the Roman Emperor Claudius, poisoned her husband with the deadly Green Caesar in order for her son Nero to ascend to the throne.
