• Fantasy Over History. The world is inspired by the history and myths of ancient Greece and the classical world, but it is not a historical setting. It blends historical elements with those of myth and traditional fantasy to create something new.
• An Age, Not a Time. Arkadia is not rooted in a year or bound to a chronology of events. The world is painted in broad strokes that depict a sweeping age defined in relation to its mythic past.
• Bronze Before Iron. Arkadia exists in an age of bronze. Many weapons, armour, and items are different than those you would find in traditional fantasy. Instead of finding rapiers and crossbows in this world, you will and take up the spear and sling.
• Ancient Magic. Though the spells you will be casting here are familiar, the style of magic is mythical rather than medieval. To this end, I encourage you to instil your spells with mythic flavour.
• Age of Heroes. Though the presence of the gods can be felt throughout the world, they are distant in a world shaped by the reverberations of their myths. Though their presence and the echoes of their deeds can be felt throughout the world, they are no longer physical beings walking among mortals. It falls to mortal heroes to take up the torch and decide the future of the world.
• Many Gods. Though certain races, places, and classes in the world are connected to specific gods, all gods are worshipped in all places. An Illyrian sailor might pray to Thessa for fair winds and calm seas before embarking on a voyage, just as an Ithean youth might pray to Lyria for their affections to be returned.
• Gods at the Source. All magic in the world flows from the age of gods. As in Greek mythology, all supernatural or fantastical elements in the world — monsters, magic items, and even your heroic powers — are believed to ultimately stem from the gods or the titans.

I like Grecian style mythology and bronze age era fun times. But this is a little light on detail. Is there anything else you can say about this idea?
