Regarding the Lines of Protection in The Rithmatist - is the protective field generated by them as the lines are completed, or…?
As with most things in The Rithmatist, the lines’ effect starts when the person who draws them imagines the effect taking place. There is a mental connection here. As you are drawing, until you are finished, there is nothing there - unless, sometimes, there might be if you imagine it to be there. The Rithmatist is (mostly) consistent with the Cosmere rules.
