I remember the first time that I saw this creature below the Bone Palace. It terrified me. In reality, a lot of things terrified me in my early days. This creature triggered every one of my nightmares because, truthfully, there's nothing warm and fuzzy about it. I don't know whether it was the lack of expression in its eyes, the pointed legs, bulbous body or the weird stuff oozing out of its chest that did it. I just knew that I didn't want to be anywhere near it.
Here's the thing. As I studied them more and more, the fear lessened. I realized that they were just another elemental creature that had a family, friends, and was just doing their jobs. The lack of expression didn't mean that they were horrors. It just meant that they needed other methods to communicate with each other. It was just different and... different doesn't mean bad. It just means... different.
Like many of the other elementals that I've come across, he's a necessary part of the community. The oozing membranes that comes from his chest is used to repair the cave system and promote growth. As the ooze melds into the rock, new plants are grown and fortifies the area. These plants also provide food for other elementals which, in turn, causes more elementals to settle in the area and promotes more growth.
Like us and many other creatures in the world (elementals included), there is a cycle and we are all dependent on one another.
