Grootslang

According to legend, the Grootslang is a primordial creature as old as the world itself. Tales state that gods (who were new to the crafting of things) made a terrible mistake in the Grootslang's creation, and gave it tremendous strength, cunning, and intellect. Realizing their mistake, the gods split the Grootslang into separate creatures and thus created the first elephants and the first snakes. But one of the original Grootslangs escaped, and from this first sire all other Grootslangs were born.
