Designed for play with the 5th Edition of the worlds most popular RPG!
Traveling to the far reaches of the Barren Wood is perilous in the best of times, and these are not the best of times. Here, in the forest's western eves, the trees are old, with tangled roots deep in the ground. Here too, the fey still roam wild and free. Ancient ruins, many predating the Winter Dark, lie buried in cool deeps, their halls and towers abandoned to the wilderness and to time. But here too, in these dangerous environs, Unklar's folk have fled, making hidden holes in dark places. So it is with the small and the powerful.
The most famous of the ruins is the Old Ziggurat. Built by the Aenochians, its many levels served the priests of that ancient empire some 1300 years ago. The Old Ziggurat lay empty for many years, but that, so the tales relate, has changed. The Bard Erikendous has come from the lonely paths of those western eves with stories of dark roots in that old place, as well as creatures, of Unklar's servants, making their abode there. His tales, crafted into song, are of a Witch Queen. Few of these creatures lived in the days of darkness, but they were dreaded servants, foul and mean women who ate the flesh of their victims.
The Old Ziggurat is a foul place and any would-be heroes willing to enter this abode and challenge the inhabitants must gird themselves for desperate battle against both the arcane and mundane. For here reside one of the Witch Queens of old, and she has surrounded herself with the remnants of the Horned One's armies and the cohorts of those wrecked and ruined in the foul pits of Aufstrag.
