This has been a bone of contention regarding BioWare's story crafting for me. I think non-force users should have an alternative story and perspective while playing through because they certainly don't really fit anywhere in KOTFE or beyond, except maybe as the alliance leader, but they can arrive there another way. I don't believe that Valkorion would be so desperate to possess the mind of a non-force user albeit a non-force user may enjoy having force powers. I know in the movies you have non-force users in battles alongside the Jedi fighting Sith and vice versa. But, when you are talking about the most powerful of the Sith ... Valkorion and his children, I can't see a non-force user actually winning. I mean Hans Solo shot at Darth Vader who wasn't the most powerful of the Sith ... and, well, we see how that went. Personally, it would have been cool if the Agent, wakes up out of carbonite and has to go behind the scenes of Zakul ... and if your choices from the first three chapters actually continued in the expansions. For example, at the end of the Inquisitor story you can keep, release, or cleanse the force apparitions within you - but, if you keep them against their will you don't get any darkside points nor does that story play out at all. The one reason you were powerful enough to defeat Thanaton is because of the combined power of those spirits. Keeping them, would essentially make you the most powerful Sith in the Galaxy. Then, when Valkorion forcewalks with you ... your character should be able to bind him in the end. Also, given he co-exists with the other spirits in your mind, they should make an appearance at least to reference your story. The end of the Inquisitor story was epically powerful; You rose to power from slavery, learned of your ancient Sith lineage and of your ability to consume force apparitions to increase your power. Why wouldn't you jump at consuming the Emperor? It's like you forgot you are a ghost eater ...
