The Winter Grove is an ancient druid's grove that lies within the Barrowood in Cheliax. Ruined and blackened, the grove predates the old empire of Taldor, before the rise of Cheliax as an independent nation.
Rumours say that within the grove lies a summoning circle of ancient origin. Furthermore, within this circle Abrogail I made her dark dealings with Asmodeus. In recent times, locals to the region have witnessed members of the royal family making regular (but secretive) visits to the site, always bringing sacrificial victims with them.
