assaulting the cathedral

Astigi Flashfire Campaign- Astigi- Narbon City- Day 2-  A large group of Stygian militia rush the front door to a small cathedral of the Emperor Triumphant.  A lone sister of battle bars their way.  The battle sister throws grenades and empties her bolter into the oncoming horde all while reciting aloud the litanies of hate.  It is not enough to stop them from gaining entry not on her own but it is her duty.  And only in death does duty end.
