At some point in the First Era, the embattled clergy of the Quenching Grail constructed the citadel of Pantherfang Chapel along the banks of the Panther River in Blackwood. This fortress served as a bastion of faith, and within its walls the Quenching Grail built a grand cathedral. Although the order was eventually disbanded, Pantherfang Chapel continued to stand for many centuries.
Circa 2E 582, Pantherfang Chapel was available for purchase as a private residence. By 3E 433, all that remained at the site of the former cathedral were the ruins of an abandoned Legion fort known as Fort Redwater.
