Mara Vance
Licensed grounder and central observer
A precise, dry-witted observer trained to say only what the evidence can support. Mara has weathered hands, trusts surfaces before overlays, and has built a life around never repeating the error that destroyed her family’s work.

Mara begins by treating truth as personal discipline and procedure as a substitute for connection. Her journey forces her to understand truth as shared infrastructure: something communities maintain together, sometimes at devastating personal cost. Reaching June again matters as much as proving the divergence, because the person Mara most failed to observe was her own sister.
