Giants in the Earth

A setting where giants rule the earth in a society similar to ancient Greece. Humans and other player races are enslaved by the giants. You escape your bonds and work as a rebellion to fight against the giants and liberate your people from their domination. There are possible allies and places of refuge. One is the druids and fae that keep the forests wild and resistant to giant incursion. Another is the dwarves and artificers who live underground and in caves and create constructs to battle the giants.
