Silen is a guardian figure, and has grown into his role as such after years of crossing harsh terrain on many journeys with his rider. He is amiable, friendly, and tame towards humans; that being said, while he does not start fights he will end them, and usually all it takes is standing his ground and baring his fangs. His is big and knows how to use it. Adaptable, brave, and with a good sense of humor, this easy keeper is the kind of Tokota you want by your side when all your luck has run out.
