Raiders of the Lost Tomb
Tortles are a race of tortoise people from the area known as The Snout of Omgar. Here they are born in forts constructed by their parents to protect them. When they can walk and leave the fort, their parents spend time passing on all of their knowledge to them. Then they are sent out into the world, to learn and add to the knowledge of their people.
Tortles live for about 50 years. Towards the end of their life they get the urge to mate, and return to The Snout of Omgar.
Tortles have no gods of their own, but often embrace the religions of others during their travels. They do have an almost religious view of the sun and moon, perceiving them as eyes that watch over them and protect them. This is why a tortle will be reluctant to go underground. Lucky days are those where the sun and the moon are in the sky together.
