Vicious and bloodthirsty, Len easily comes across as a savage at first glance. With a playful way of looking at violence, honed by a lifetime spent hunting, they simultaneously exude reckless bravery and bloodlust. In the aftermath of any battle, they are likely to be casual, even dismissive of death or injury, stating that anyone who steps foot on the field of battle accepts the risks that come with it.

Surprising some, then, is the intellect, and even gentleness, concealed behind her piercing green eyes. While they do not hesitate to kill, they can show a surprising tenderness and protectiveness when appropriate. A number of more 'civilized' skills were instilled into them by their older brother Korokas, honed by their focused and alert nature, including the ability to read and write, knowledge of ritual, and abstract thinking. Unlike their brother, however, their overriding ambitions- at least for the time being- largely begin and end with finding Korokas.

Skills or not, their attitudes are hardly typical of civilized peoples. Beyond their bloodthirsty nature, they can be immodest and careless of social conventions, having no difficulty with nudity, displaying affection, or acting how others might consider rude in social situations. Further, she has no difficulty openly displaying disgust and disdain for others, though even so she is capable of concealing her venom where it might be necessary.

If one were to catch them on their own, they would find that the Dwarrow is actually somewhat vulnerable to occasional bouts of melancholy and getting lost in their thoughts. Should they have the opportunity to relax on their own, one might find them lots in reverent awe at the stars in the sky, or the distant thrum of a thunderstorm. While hardly a devoted member of the Dwarrow moon-cult, they show their own sort of reverence for the night sky, often tracing the constellations or stargazing before they drift to sleep.
