Reverse City
Location in Norwin, the mythical, minuscule city of the Frool Forest where tiny Green Gnomes live. It is mentioned in the first chapters of the First Light by the Paglot scouts in the cave of the Torry Mountains. You have to find the shrinking potion in order to downsize yourself to enter the Reverse City, yet there is no explanation of how to get out of there, thus risking anyone of being stuck in the tiny city forever. The Green Gnomes possess the last secrets of the shrinking potions and the much coveted key that allows to enter the realm of the little wizards, prohibited for any mortal in the whole Globiuz.
