Darkness in the Delimbiyr
Hellgate Keep, formerly known as Ascalhorn, was a city of evil on the northeast edge of the High Forest. It was destroyed in 1369 DR when the Harpers used the Gatekeeper’s Crystal, and is now overseen by the treant Turlang, and his fellow druid-protectors. Ascalhorn was founded by the Eaerlanni elves in the northeast of the High Forest on an area known as Ascal’s Horn, to protect the boundaries of the kingdom. They gave it to the Netherese refugees after Netheril fell.
Wulgreth, a Netherese wizard, summoned demons to the city in 820 DR. In 880 DR, this prompted his many rival wizards, with the guidance of the fey’ri, to summon devils to counteract the demons; but in 882 DR the demons won the battle and conquered the city. The demonic forces continued their rampage, destroying Eaerlann and Ammarindar.
In 1368 DR, the Azure Bear tribe, led by shaman and chieftain Tanta Hagara, marched on the fiend-ridden fortress, in an attempt to cleanse their lands and reclaim the tribe’s honour – however, nearly a year later, the tribe’s traditional barrows and huts lay in ruin, and for all purposes, the Azure Bear tribe was destroyed in this failed assault.
