"If one's mask is not perfectly wrought, if one is not at all times thoroughly conscious that it is a mask, then trouble is to be expected, and the dangers of identifying with such a mask leads to dissociation of the personality (i.e. the gradual erosion and disintegration of the mask), thus denuding the magician and rendering him the prey of hostile and vampiric forces.  His mask may be seized, 'patched up', imprisoned, and used by larvae as a zombie or a decoy to inveigle into the Tunnels the magician's unsuspecting associates.  The intervention of a force from beyond the Abyss can alone salvage such a wreck."
