Ulca Felya was the central shard in Civcraft 3.0. It was designated as the cave shard, full of giant caves and caverns spread throughout the shard. No country held territory in this shard, however, a marketplace was set up at 0,0 by 3.Road, who also set up roads in the cardinal directions leading to the portals on each side of the shard.
Not much was known about this shard, except that its main purpose was for mining ores, where common ores like coal and iron were in abundance. Sometimes one would get more rarer ores like diamond, gold, redstone, etc., but they were not as common.
