Abrulges
Abrulges: One of several demons named in association with Pamersiel, the first and chief spirit under Carnesiel, the infernal Emperor of the East.
Abrulges holds the rank of duke, and he is reputed to possess a particularly nasty temperament. According to the Ars Theurgia, he is both arrogant and deceitful and he should never be trusted with secret matters. Despite this, however, his naturally aggressive nature can sometimes to be turned to good. Abrulges and all his fellow dukes can be used to drive off other spirits of darkness, especially those that haunt houses.
