Just replayed some KOTOR 2 and want to do a Peragus style mission. Has anyone done this investigation/mystery/mass-murder story?

I've thrown some ideas around already, some greatly ripping-off the KOTOR story:

1. This time, have a mining accident reveal some miner or slave that force powers. By saving others, it makes them a target of taking prisoner to be sold to the Empire, Hutts, etc.

2. Some digging awakens some creature or creatures or some other horror movie stuff.

3. So I'm trying to come up with a sabotage scenario that implicates a rival mining company or Hutt Clan. I think this may take away from the mystic mystery out of the story but maybe I'm about that.

Any help with some cool ideas would be appreciated.
