Rogue Trader - The Hos Dynasty
Dionisio of Navis Nobilite House Pazzano
Head Navigator, but only by his title. He's viewed as a joke
Navigator Primaris of In Purgatio Lumen
The official Navigator of the In Purgatio Lumen, he is an elderly corpulent man that takes no pain to hide his mutation from others. Theoretically in charge, he prefers to “delegate” the Navigation tasks to his subordinate so that he can “learn from the master’s experience”.
