Ominis Gaunt, Duke. Ominis Gaunt, is considered to be vastly different from his counterpart, Sebastian. Where Sebastian is considered a ladies man, Ominis is sweet and very closed off. Ominis is actually rather sweet, when he allows you close enough to see it. He doesn't care for nobility, often seen to be going against them, simply because he enjoys it. When he meets you, the maid, he's kind and a little flirty—something that takes you by surprise. But anything between you is forbidden.
