A tweak on the earlier post about The Outlands, here describing the nine civilized lands tied ethnically and quasi-historically to ancient Greeks, Egyptians, pre-Roman Celts, Vikings, Han Dynasty Chinese and various mythical peoples like dwarves and elves.
In terms of “religions,” see: Celtic pantheon (PHB5e p. 298), Dwarven gods (PHB5e p. 296), Egyptian Panteon (PHB5e p. 299, esp. Thoth), Elven gods (PHB5e p. 296), Greek pantheon (PHB5e p. 298, with seasonal festivals to each deity) and Norse pantheon (PHB5e p. 299, esp. Odin, Thor and Tyr).
