Arrak
For 1200 years, the world of Arrak was a haven of peace and prosperity. This was the result of a once in a century event known as the Passing of Pelor's Light. It is a comet, a gift from Pelor, that radiates positive energy, which blessed crops, healed the sick and kept monsters in a magical slumber.
There is a celebration for the 13th Passing of Pelor's Light. The comet emerged into the world and rises up to the sky. As it reaches its peak, however, tragedy strikes. The comet shatters into thousands of shards! It fell across Arrak, flattening homes and cities, and destroying governments and economies. Monsters are now awaken and start ravaging the lands. Everything is thrown into chaos. Till this day, no one knows how or why the event, known as the Lightfall, happened.
46 years have passed. The world is slowly recovering. Heroes have come and re-established cities and nations. The towns and cities act as beacons of light in the darkness. They are safe-havens, with organised armies and militias, as they protect the people against monsters and dangers that lurk in the hills, woods and dungeons.
