A lot of people are confused about why the DJD could just storm the Lost Light like that. The DJD doesn’t know either. But Tarn’s convinced everything’s fine! Really!
Also, they’re apparently just a bunch of violent, very insecure kids and Tarn is their personal motivator, even though he’s just as insecure.
Why did I even color this, I don’t think anybody who isn’t me thinks this is funny.
