now i really hope this isn't right, but i gotta say it

kalina said ragh barkrock, not lydia. lydia has experience with these things, she knows how to seal it and she's pretty cognizant and capable at the moment so she doesn't need ragh to explain on her behalf. maybe kalina just said ragh because he used to be infected (and he wasn't born with it so we can assume lydia wasn't) so she knows him better, but. lydia's already occupied with the gem in her chest. IF the same ritual needed to happen to seal the shatter stars again, lydia wouldn't be strong enough in her current state since she's weakened by the gem. gorgug's strength score dropped to 18 since taking more levels of artificer. ragh still has a +5. as far as we know the closest person to the bad kids who COULD have the strength to fuse with the gem is ragh, who also has some experience with it already. and if he did he would experience the same illness as his mother if not worse.
