Grand Barrier

The Grand Barrier is a supernatural, impassable obstacle bordering roughly one half of the entirety of the demiplane of Lamasery, and its creation is considered one of the true Miracles performed by Arvana Sanys.

Creation
As the Grand Barrier's existence predates the known history of any of Lamasery's resident races, its creation is a hotly contested topic for many scholars and philosophers.

Features and Manifestations
The Grand Barrier takes many different forms along its expanse, ranging from an invisible yet slightly pliant 'wall' in the extremes of the Eastern reaches to a swirling fog which deposits those seeking to pass through it back at their point of origin in much of the South. Other notable features include:
 * A short distance of approximately three miles, near the Oseudan city of Thryfeld, along which the Barrier takes the form of a glowing wall of small, interlocked hands;
 * A stretch of nearly ten miles south of the former - now abandoned - Tonveran capital city which is a perfectly reflective wall of liquid;
 * The fifteen mile region near a famous battle ground which has become known as a particularly haunted region, wherein the Barrier takes shape as a howling gale force wind which seems to whisper of the deaths of any who try to pass it, stealing away the sanity of most who make such an attempt;
