Dear Beowulf,
Oh wow. That does not seem fair, but I will aid you in your time of need. However, I can not promise that me and my army will be as effective or helpful as you were when you aided my men. You see, my army is still crippled and recovering from when Grendel and his mother attacked. I will still always be by your side when ever you need anything, but I can't make any promises and I would expect any miracles.
