Query: hard to follow action story

I was hoping for a more thorough explanation on how the Psi-Corps got started - what motivated the mundanes and the telepaths. How did something that should have started as a gulag get so powerful?Instead we get an action story. That in itself is not bad, but there's not much character exposition so I couldn't tell much difference between the Psi-Corp telepaths and the underground telepaths.A wasted opportunity that could have been much more.
