Shards of Yuna
Our world is one of floating islands in the sky. These Shards are the only lands that the people of Yuna know. These shards come in all shapes and sizes from ones barely large enough for a single mage's tower to the mighty city-state shard of Eaglespire. The people of Yuna are not cut off however, they have developed airships which connect the different shards and allow for travel, commerce, and of course adventure.
