Yeah, that's a pretty valid reason xD 

OH RIGHT, the chronicles! Bless you for doing Act one. I can jump in for Act two if you'd like so you can focus on character stuff? Or do you want to do both Acts one and two? 

Lysa did some digging of her own in both Jedi and Sith archives, so she believed that the tomb she visited was the beginning of her journey to find out more about the True Sith. When she found out, she called Yerbol to hopefully persuade him to join her "journey of discovery". Thankfully Ari ended that thought, seeing as I think Lysa would've only fallen even farther to the dark side :/
