I have not played fire emblem 3 so i do not know the full story.
I read on wiki that after the war gharnef was killed yet he survived because he sealed his soul in the dark sphere and when he hears of hardins depression he disguised himself as a merchant and sells him the darkspere which corupted him.
But how can gharnef sell hardin anything if his soul was trapped inside the darksphere because i think hardin would have noticed if an orb was trying to sell itself.
So is this a plot hole or just my lack of knowlege about fire emblem 3.
Another question should i downlaud fire emblem 3 or is it too old compared to the other games.
