He can go to any place on Aiers in a matter of seconds to accomplish the will of the conjurer, bring abundance, help in finding hidden treasures or in robbery, and is not a demon of evil but good nature, being mostly indifferent to evilness. He is depicted as a man riding a winged horse, and is said to be beautiful."
In the Dark Legion and the Demonic Republic, Seeres was the treasurer of the Dark Legion, and the one to provide the much needed money to the endeavours of the Dark legions, and as such, was deeply pragmatic in the solutions to provide the money, and to collect the taxes.
