In my fictional universe. The Modern Races time began with a brutal war that eventually sent nearly all of them evacuating the Heartlands in the southern Hemisphere known as Lortai
most of them went North across the great expanse of the Altirian Ocean (the more prominent races call it that). For the 6 races (last I checked) who made the Exodus north, only two had come across the chain of volcanic islands that would come to be known as the Stranded Isles.
The Kredoc (lizard men like Argonians in TES but more dinosaur-like) attempted to establish permanent residence on the chain, but soon realized they face harsh weather (monsoons, hurricanes, volcanic eruptions) a whole slew of lethal diseases, and very dangerous Kvari (the world of Soni's term for wildlife).
Their efforts weren't exactly wasted, as they found something on the largest of the isles that would soon be a culture-spanning necessity, the Ymithiir Fruit. It grows on vines along the shoreline, and is a very potent euphoric drug when fermented and boiled. As technology progresses, the common "consumption" of Ymithiir involves a steampunk-style pipe with a tiny boiler at the bottom.
