Baulder was holding onto the dome, as if his life depended on it. Well, technically speaking, it kind of did. Zenia on the other hand was trying to figure out how to act. She didn't really receive any direct orders, or even a single tip on what to do, but seen as they had to do something, she had little choice in the matter at this point.
In her experience, there were multiple ways to defeat a tough foe. Option number one was to grit your teeth, and beat them all, however, with the sheer amount of people she'd have to defeat, that was just about out of the question. Calling backup would be another option, but seen as they didn't really have any, it was between her and Baulder to do this, but the latter was kind of in the middle of something.
