The Merry tales of Grook and Friends (title pending)

The city of Adverdale lays within the Northern mountains, strategically placed to prevent monster hoards from flooding into civilised lands.
As the latest hoard approaches the Bulward, a 90 foot tall wall that is 30 feet thick streaching a distance of 500 feet, the first line of defence, the Lord Captain Orsick Stonecutter, sends out a request to the Southern cities for aid in the form of Adventurers.
