In 2087 the rivers, lakes and sea dried up. The rain stopped falling and the planet turned to dust. Animals started to decline in numbers by the day, meat was scarce. The famished humans roamed the land killing every single beast in sight to feed their hunger. Only the chickens remained, thousands of them locked up in pens row by row churning out eggs by the hundreds of thousands per day. A human would trade a bar of gold for an egg and the pens were heavily guarded to keep the chickens safe from the famished hordes roaming the wastelands.
