Max Schreiber

Max Schreiber is another of Gotrek and Felix's staunchest allies, his mastery of the power of magic more than making up for his rivalry with Felix for Ulrika's affections.

Suave, intelligent, and well-educated, Max is a natural rival for Felix, who resents the magician's romantic interest in the Kislevarin noblewoman Ulrika.

Romantic rivalries notwithstanding, Max has become one of Gotrek and Felix's most enduring companions, and his magical ability -- which is growing more powerful all the time -- has often saved them from death, for he has the power to protect and heal as well as inflict harm. Like Felix, Max is something of an exile, as his obsessive research into Chaos got him expelled from the Colleges of Magic, and has earned him enemies in the Empire.
