Changes

After retrieving the [[Hand of God]] from the Nazis, the Woman of Letters, [[Delphine Seydoux]], boards the ''[[USS Bluefin]]'' back to the United States. Before the submarine sets sail, she places special warding sigils around the hull that are connected to a sigil carved over her heart. The sigil, taught to her by Clifford Henshaw; her mentor in the [[Men of Letters]], protects from supernatural interference, including angelic, hence Lucifer is not able to make the time travel trip past the hull of the sub. As the sigil's magic is connected to the user's heart, its power lives and dies with them and can only be deactivated by killing whoever the sigil is bound to.
