Initially a timid and often tortured fire and thunder wyrm (dragon in our tongue) crossbreed who intends to protect his brother,  Tonnerre, from any harm. Until the day of the escape, after Tonnerre falls behind, he grows mournful and fears the worst possible things that could happen to him one thought after another as the journey to Yerach continues. Throughout his journey, he becomes more stern and determined to rescue his brother. (Try an Elijah Wood-esque voice)
