Recently elevated to Inquisitor status after serving as an Interrogator in the service of Inquisitor Van Vuygens. While Van Vuygens combs the very edge of Imperial space for alien civilisations, Al-Subaai’s role is to search for alien influence in the populated worlds of the sector. Probably the youngest Inquisitor in the cabal, Al-Subaai is deeply pious, and he looks it, usually attending gatherings in a monastic habit worn over sturdy, practical carapace armour.
Al-Subaai believes that everything in the galaxy is connected and that the various alien species and their depredations are part of a larger web of hostility generated by the galaxy. The galaxy, Al-Subaai believes, is reacting to human occupation like a body reacting to a disease. To him, aliens (as well as all creatures of the warp) are symptoms of the galaxy’s enmity towards mankind. Al-Subaai therefore advocates the destruction of all aliens, especially those who influence humans. He considers his remit to cover not only alien-influenced cults and corruption, but also the trafficking in alien creatures and their technology. Anyone dealing with aliens or their artefacts is an enemy of humanity and nothing gives Al-Subaai greater satisfaction than to hunt them down and subject them to whatever punishment the cabal decrees. To Al-Subaai, the Propheticum Hereticus Tenebrae is the handiwork of alien manipulation.
