Lands of Rowia is a MOC-based fantasy world called Roawia which is populated by the members of the Merlin's beard forums. The world is broken up into four factions: Garheim in the arctic north, Lenfald in the forests of the northwest, Loreos in the central desert and grasslands, and the Outlaws who are scattered throughout the land, but are more concentrated in the southern mountains and swamps.

Each participant creates a character who will represent them in the game. This character can be anyone; a merchant, a power-hungry baron, or a simple farmer. Once you've decided on your in-game persona, you can build MOCs that help to tell his/her story. You can also build MOCs that will help increase your status in the kingdom as well as your faction's standing. This occurs through various contests and challenges, described further down. Choose your faction wisely, and work together to make yours the most powerful in the land!
