Barrier

The Barrier is a dome of unknown origin and unknown composition. It prevents all living beings and objects within Tellura from traveling beyond it. Some believe it to be a zone of safety, wrought by either a divinity or some lost race to protect all within it from whatever lay outside it. Some even believe that there is no outside. All that is truly known is that the Barrier exists and no one has ever succeeded in passing through it.

The barrier is not static, but rather a fluid entity. Occasionally barrier shift events occur; undulating inward, to cut off border lands or swelling outward, exposing territory that was previously unexplored or isolated for a long time. There are rumors of rare artifacts of great power and treasures found in these shifted areas but they also attract dangerous creatures and should be explored with caution.
