GURPS Ice Age #3: Valley of the Giants

Travelling with the Flat-Faced People, the two Real People take part in a ritual and drink a sacred tea. Ghaagalk feels the love, while Doof has his mind greatly expanded. Afterwards, they’re taken to meet with a wise leader known as the Plungar. He presents them with an unexpected gift and tells them the location of the sky metal, a land inhabited by giants.
