I reckon in KOTOR III, you play as a Revan returning to the galaxy, only to find it changed, with the Exiles actions creating ripples through the Force even now, and only the loyal HK-47 to fill you in on what happened while you were away, and to explain why you have to start at Level 1 again, Revan went out of the Galaxy completly, where the Force does not even exist, and so lost his force connection for a while. Or possibly the Exile Searching for Revan outside the galaxy? That would explain some things.
