We're not exactly sure what the Abbey needs defending from, but these scary looking creatures on the right of this picture certainly warrant some extra security. Unfortunately the knights on the left may be outmanned by this group. And their swords and shields look to be no match for the giant spears of their enemy. 

The enemy's leader up front is wielding a BrickWarriors Crescent Axe; a custom LEGO weapon that one knight looks to be getting a rude introduction to. The enemy creature in the back right of this picture is carrying a skull and bones as well as a BrickWarriors Scimitar.
