Much as the first level of Yliakum is known as The Dome, the second level is known as The Barn, presumably because it is one of the two main levels that support serious agricultural development and provide food for the other levels. Below it lies Far Ground, the third level.
There is still enough light to grow good crops on this level. Some beasts are raised here that do not thrive in the hotter Dome.
Locations of Note
The mint that creates all money used in Yliakum is on this level.
