House Sīna

The Sīna House is a family which has, for centuries, been dealing with the Al-Ghaib (الغيب) or the "Hidden World."

The family has split itself into three-folds; Aabir (the dreamers), who interpret dreams, Aasir (the controller's), who deal with jinn, especially the mischievous types, and Taahir (the cleaners), who deal with possession and exorcism.
