While leaving the ruins, Walker saw that there were some interesting monsters being brought out. There were sand worms that he did not expect to be found here. However, with a little listening, he learned that they were a sub variant of the sand worm species.
These sand worms had been trapped in caverns due to earthquakes which led them to slowly develop a water affinity related to their environment. Those who survived tunneled toward the drier stone and began to live by breaking away the tougher stone and making that their nests to hide their eggs. Their eggs still needed to remain entirely dry no matter what.
The other monster that Walker saw was something called a gravel spider. A species of earth affinity spider that enjoyed making their hunting webs underneath gravel. This way when something stands on top of it, they fall in to the hole allowing them to ambush whatever prey had just been tripped up.
