Maybe add a 'good karma' option to convince Tia's grandfather to let her work for the player character? If it's possible?

If your started in Gorn then getting sent back to the mansion from the forest was seriously annoying so I cut it out. To be honest, I'm not looking to do more with Tia, there is already one hidden option, and the approach to that bandit camp probably needs more rework (it's a long unthreatening fight and the mitigating conditions never seem to apply).
