from the introduction:
Little is known of the Jungles of Southlands (or simply Southlands) that covers half of the continent. Elven maps reveals all the coastal edges but rarely as deep as a mile inwards the untamed jungle.
The maps are many and contradicting, in-game and outside. The most recent maps will show The Great Mountains, reaching all the way down towards the Elven Fortress. That’s also where The Jungles of the Gods ends. Approximately 5000 km down the latitude from where The Cursed Jungle starts making twice the distance of the tropics in real-life African. Surely the works of Slann magic as the thick jungle is the best defence against unwanted intruders.
