Axel Mortmain

Axel Mortmain also know as The Magister (1803-1878) was the adoptive mundane son of late Warlocks John and Anne Shade and is the main antagonist of Cassandra Clare's book trilogy The Infernal Devices, the prequel series to Clare's other series The Mortal Instruments.

Axel was born sometime in 1803 to two unknown mundanes but was raised by two warlocks John and Anne Shade. Sometime after 1815, John and Anne were killed by the Clave as they were accused of having unnatural and illegal dealings with demons and creating a weapon that could destroy Shadowhunters.

Axel later for recompense through the York Institute as he wanted the Shadowhunters responsible for his adoptive parents deaths to be tried and punished. But Aloysius Starkweather (one of the Shadowhunters that killed the two) refused his trial.

Since then, Axel plotted his revenge against the Shadowhunters, seeing the whole race responsible for John and Anne's deaths by creating a new race, a form of Warlocks that were half-demon and half-Shadowhunter that would be superior to the Nephilum and cause their destruction.
