In the days of his youth, Moranion - of Athel Tamarha - wandered the realm of Yvresse as one of its Mistwalkers. Few could tread the fog-wreathed paths so surely as he, for he bore a Wayshard attuned to the great watchstone at the realm's heart. Thus did Moranion walk the Daemon-haunted mists as easily as he would have done under clear skies, leading ambushes of spear and bow to destroy the invaders. Though Moranion now sleeps eternally, his wayshard still glimmers with power. Those who can unlock its secrets will never again find themselves lost, no matter how far they might stray.[1a]
