Suchus

Suchus are a humanoid crocodilian race with origins not even known to the Suchus themselves. They are incredibly solitary in nature, almost only interacting with each other for the purpose of mating. In addition to being solitary they are typically sedentary and quite defensive of their homes that are typically in swampy or marshy areas where they are quite effective at ambushing unwanted trespassers. Being solitary they learn to be independent within the first few months of their lives or die trying. The first few years of their lives are spent living off instinct alone; their intelligence and morality mature as they do, graduating from being as bestial as a crocodile to being capable of speech and comprehending the concepts of right and wrong.
Suchus who grow up near settlements of more 'civilised' races may learn the languages of those people but Suchus themselves typically communicate with each other primarily through body language and guttural growls and hisses. Many Suchus who do grow up in civilisation often take up mercenary work, being valued by mercenary bands for not only their natural prowess in battle but also for their intimidating appearance which can resolve potential conflict through intimidation alone .
