All I can think is that this character should make use of the CHARLATAN'S COPE (not to be confused with the CHARLATAN'S CAPE, which is also appropriate for him).
I already have a player with a character but that name in my Age of Ashes.
Blue kobold illusionist with an overinflated sense of self. He's very good.
'The Magnificent' just means they have a high opinion of themselves. 'Maximillian' might mean more of the same, or I suppose it might be a reference to Maximillian plate, what PF calls full plate. You could make an arrogant fighter-type, or since Emperor Maximillian had people for that you might have someone who commands such. Perhaps an impossible bloodline sorcerer who makes clockwork constructs and buffs them with heroism or similar; crossblooded impossible/psychic would let you wear full plate too and perhaps not stand out as the squishy master of the constructs.
