Guardians of the Veil Rote: Unstitch
Just as a skilled tailor can unravel a garment by pulling out relatively few threads, a Guardian can pick apart the weave of a source of tass and unmake it, releasing its energy back into the Tapestry. Adamantine Arrow mages also use this rote to dissolve the tass of enemy willworkers, robbing them of a precious resource.
