I was wondering that aswell. AS I have already beat (and ferociously, at that) Ego Draconis, I went straight to Flames of Vengeance. I suppose the three armour sets are in your inventory starting at level 1 in Ego Draconis, although I haven't checked. If not, who knows? I've got all but two peices of an amazing armour set in-game, so I'm not too worried.
You might check at level 1. Sorry I couldn't be of more help.
