And yes lore-wise Alexander is a Primal. Well, maybe an Eikon who knows currently at this point with wierd definitions and all that.
Besides the mainstory, you needed to unlock and beat the 3 HM Primals (Ifrit, Garuda and Titan) after you finish "The Ultima Weapon" quest. These 3 quests are not part of the MSQ.
