Tatzlwyrms are thought to be primeval relatives of true dragons, having branched off the line millennia ago and evolved in a way that sets them notably apart. Undersized compared to their larger cousins, tatzlwyrms are nonetheless ferocious in their own right. And while tatzlwyrms are hardly impressive specimens when put beside their notorious relatives, most other reptiles can't compare to them mentally. They understand Draconic, though other languages are beyond most tatzlwyrms' limited comprehension. Nevertheless, tatzlwyrms are deeply cunning, building complex lairs and rudimentary traps.
