Marzie is one of two 'treasure hunter's' who attempted to go north through the primal area prior to Lacie's arrival. However unlike her partner whose corpse can likely be found strewn about an area within the area containing the primals where the trail of petals ends, it is not impossible that Marzie survives or otherwise never makes it that far for one reason or another, as the padlocks are still in place once Lacie gets there and all the keys are in the locations which Marzie's partner left them in. This may imply that Marzie met another fate (perhaps a Faerie related one) although its possible that Marzie did perish in the primal maze (there is enough bodies there for one of them to be Marzie). Additional evidence which suggests Marzie meeting a different fate is that only 1 body is present where her partner dies and the trail of petals ends.
