Built by the warlord Kazavon (who was later revealed to be a blue dragon servant of Zon-Kuthon) in 4043 AR, the site was selected primarily due to the presence of an ancient Star Tower and its divine connection to the Midnight Lord. The fortress was constructed around the tower.
Kazavon used the citadel first as a staging point to 'tame' the orc lands, then as a beacon to attract the orcs, and any others, to his banner. He thus reigned over his dominion for approximately 20 years, defeating all armies that were sent against him. Kazavon was eventually slain in 4063 AR by a small band led by the hero Mandraivus, who uncovered his draconic secret. Mandraivus stayed behind with several retainers to guard the castle. Sadly, an overwhelming orc force laid siege to Scarwall, putting the inhabitants to the sword, and setting off a terrible curse within the fortress. Undead horrors and vengeful spirits slaughtered the orcs in turn, and the castle remained uninhabited by living creatures for centuries.
Scarwall was eventually sacked in 4708 AR by adventurers who were searching for the fabled sword Serithtial. With the undead horrors quieted, several neighbouring orc tribes began warring with one another for possession of the ruin.
