'Michael' is an entity of unknown origins. First appearing in MAG 26: A Distortion, it appears to be a 6.5 foot tall male with straw blonde hair and a round face. If viewed through tainted glass or a reflection, its form distorts to appear to have a spindly body with huge, pointed hands that are as large as its torso.
It appears again in MAG 47: The New Door, the human form, who refused to shake hands with Helen Richardson, and the distorted form in the coloured corridors that she later got lost in. 'Michael' approached Jonathan Sims after he reported on that case, taking Helen back to the corridors. When asked if he owned these corridors, it suggested that it owns the corridors in the same way that your hand owns your stomach.
It warned Sasha about the oncoming attack by Jane Prentiss and the Flesh Hive, going so far as to show Sasha that fire extinguishers could kill the worms, and then removed a worm from Sasha. It alluded to a war that was going on, and that the destruction of the Magnus Archives would sway the war too much in one way, although it is a neutral party.
