As the commander of the Arianrhod Fleet, Rustal has a calm and commanding presence. He is capable of generating great loyalty from his subordinates, with Julieta Juris devoting her entire being to be his "sword" and Galan Mossa who threw away everything he had in order to better serve Rustal in more illegal channels as prime examples. He has an eye for talent, taking in Julieta for her piloting skills, Iok Kujan for his influence over his many subordinates, and Vidar who has a deep understanding of McGillis who Rustal appears to see as a threat to Gjallarhorn. Rustal can be quite blunt when he is admonishing his subordinates if it benefits their personal development, pointedly calling Iok a fool for his reckless actions and his failure to live up to his subordinate's expectations.

Unlike many of his contemporaries, Rustal is not a power hungry man but rather someone who work with the goal of establishing order and peace in Gjallarhorn's domain. However he is absolutely willing to use force and underhanded tactics to destroy anyone who threatens his interpretation of order and peace.
