The forest of HalÃ«fas is a strange place indeed. It has long been inhabited by the forest elves, a race of elves descended from the high elves that have lived for over 9000 years isolated there. This wood is patroled by a groupe of expert rangers who know the forest well, Tred lightly and unthreateningly here for you may find your end in Hathil’S arrow.
Actually a real-world fungus, just heard about it. A fungus that tastes well and all, no ill effects. UNLESS you consume some beverage, even 3 (three) days after eating it.
