Septimus, who is almost always only referred to as Oubaas, is the caretaker of Hillside Heights and Hilda's faithful husband.

He often calls people by his own incorrect variation of their name. For example, he calls Vince 'Mince' and Charmaine 'Charlemagne'.

Whenever a ceremony is held, he likes to take the opportunity to 'utter some winged words'.
