She asks Dr. Anno about the Church situation, whether he believes it would bring trouble to the camp if she meddled. (She's leaving the smugglers alone, though!) Carefully assembles an outfit to do triage in. Reads. Studies guns. Thinks about spellwork; she wants to stabilize an interaction of Force and Influential Domain for area control, and rederive Lantry's Preservation, especially given the utility and fragility of technology.
