Piet von der Geest is the current director of the Mutant Commission Office. He is South African, specifically an "Africaner of the old school", and his attitute towards Mutants is largely shaped by his experiences during the apartheid. He does not believe in harmonic coexsistence between groups defined by genetic differences and holds that one side will inevitably come to dominate over the other eventually.
At some point, he had his "ultra-secure computer, inside the MCO’s ultra-secure intranet" hacked, so it "changed his background image to a movie of two naked, ugly, fat guys having gay sex", and it lasted "four months". Amelia Hartford is one of a dozen suspects for that.
