I haven't read all the material, but I had an idea for a girl to live in FledSpar, It might be a bit far fetched though so tell me what you think
was a woman pregnant with a baby girl. The woman was a devote member of the Panthiest church. She found out her daughter was cursed by being a spirit of earth (ie.dirt,stone importantly sand). The mother thinking this was a curse from The BellRinger, or The Omen (Not exactly sure the meaning behind these two) decided she had to get rid of the baby. Being a devote follower of the gods she put it in their hands. She traveled to Feldspar, and after saying a small prayer left her baby. The baby would have died if a creature called The Sacert and it's rider didn't find her. This creature was thought to be extinct. The man took care of the baby to the best of his abilities in the barren land. He brought it food (mostly grass and the like) and brought it to water. The baby grew up with him raising it. Eventually the man died, and the girl inherited the Sacert to look after. The girl lives in a large oasis that she has built up for herself.
The Sacert
The easiest way to describe the Sacert is that it is a dragon type creature. It can fly and has scales all along it body. It's a sandy color to help it fit into it's natural surroundings. It has dual lungs. One breathes in oxygen, the other breaths in sand (I know its kind far fetched). This allows the Sacert to dive down into the sand to hide. It breathes through holes on the sides of it's neck and doesn't have a mouth on it's face. The mouth is on the stomach and it has very heavy large feet so that The Sacert can drink from the large rivers while holding itself steady in the waters. The weakness of the Sacert is actually it underbelly. It's softer then it's hard scales and can be pierced wh=with a sharp blade.
I'm less interested in the girl and the Sacert, and more interested in the Sacert as an idea for a animal living in this world.
