Once upon a time a group of mean old orcs sauntered into Little Plod's moot and declared a new grubbing pit thereupon.
Little Plod was so incensed he challenged the orcs to a Grudge Tourney in their favourite sport: Blood Bowl.
Orcs can never resist a challenge, but little did they know that Plod had a few handy friends who knew how to handle their balls.
Let the tourney commence!
N.B. this also has greater significance in the whole ongoing battle of good Vs evil.
