You have The Name of the Lord in your set-aside area.

Voilà. Successful Block.
EDIT: Forgot to post the ability.

Set this fortress aside. If you have initiative, you may interrupt the battle and place your Hero on this fortress. Hero is protected from effect. Each time you rescue a Lost Soul, return one Hero to your territory. This fortress is protected from discard.
