Out Of the Abyss

You are doing your usual guard duty in one of the towers when you see a prison break in progress. You raise your horn to your lips and blow, but it is drowned out by a scream up above. You look up a see a gigantic demon bird flying around causing chaos. It's a vrock! You can either engage it in ranged combat using your crossbow or you can run downstairs and engage the prisoners in melee combat.
