Mara drew four routes on the frame plate with a grease pencil.
Grease pencil this time, and no chalk, because the plan would have to stand for days and chalk rubbed off when Doss leaned on the plate. She drew them in four colors from the yard’s pencil box, one beneath the other, across the plate’s lower half.
Blue: the Tern to Meridian. Sera. Mara. The spare seat. Four days.
Red: Lorn’s return. Anwen and Lisan, with Nemi’s technicians from the Founders’ Quarter on the valve. The first sealing. The first outlet’s old route closed and the new return opened.
Green: Tal. The mirror iron for Tal’s return, crated by Gell and Brisk in the yard store, carried by Odren’s patrol. Odren had a new cutter, borrowed from the Meridian squadron while Vigil’s sister ship was repaired. The Board had asked him to escort the metal as far as the Tal gate, where Tal’s own guard would take the crates while he went on to Meridian to return the cutter. He had said yes, in writing.
Black: Eshel, at the Cinder link. The common measurement point.
Beside each route, she wrote who could stop it.
Blue: Sera. Red: Lisan, or any technician on the valve. Green: Odren, or the cutter’s stop-person. Black: Eshel.
