Demonology is the study of Demons. Students of this practice are able to summon demons at will. The only known practitioner of this study is Zanmaron the Red, who lived over a hundred years ago. It is possible that people such as Wizard Grayzag, Relenor and Wizard Taloram are demonologists too, as their work involves demons heavily. Ellemar was a Saradominist demonologist who was executed by the Church of Saradomin for practising it.
