All right, back to work. She doesn't really - want to - but she has to. It's just occurred to Thellim that she herself may only have months remaining before her "first lunar eclipse past the age of twelve" hits her and possibly turns her into a submissive. She might have only that long to find a solution on at least an individual level, and if she can't find one, she would have to - pretty seriously reconsider suicide again. Maybe she just drew an unusually bad world to end up in on her first draw from a permadeath roulette.
Assuming, once again, that all her wild theorizing is correct at all.
If their first lunar eclipse has substantial effects on kids not being turned into mages and psions, somebody ought to have studied that, right? Somebody? Please?
Not quite tracking the distinction between the way she's thinking about Earth herself, versus the way Isabella talks about Earth, the first thing that Thellim types into Google is "effect of moon on personality".
