I want to run a game which as both an historical and geographical background matching our own reality. Description of lore should be quite accurate, but can have a pinch of myth, legend and magic as perceived in the ancient time (oracle, healer, tribe's shaman, witches, healing plants, deities, ...). However monsters and powerful wizards should be only present in oral traditions.
The goal is to run a game that can help to acquire knowledge about ancient time while having the fun of roleplaying.
