This tumultious climate of Hellgate Keep continued to provide adventuring activity. A group of Harpers infiltrated the city using cloaking magic and revealed that Tanta Hagara was actually an annis. This revelation did nothing to hamper the Blue Bear's respect for their powerful chieftain however, and the city responded to the unmasking by attacking caravans en route to Sundabar. In addition, a few expeditionary forces of tanar'ri were sent to harass the Citadel of the Mists, Sundabar, and Silverymoon. Tanta Hagara informed her "loyal troops" that gates existed in these cities that could allow other tanar'ri to "join us in the glorious battles to come as we take control of all of the North."
Alustriel cast powerful magical spells in the defense of Silverymoon against the raiding tanar'ri, and the city itself suffered no damage from their attack. The Mistmaster of the Citadel of the Mists likewise aided in the defense of his citadel, though reports still rage about the assistance of the treant of the High Forest.
Sundabar suffered from Hellgate Keep's attack, as the fiends broke through the walls and raised havoc along the city streets. While adventurers battled the fiends, Helm Dwarfriend let a large contingent of the city guard to drive out the remainder from Sundabar. Still, the fiends left the city with the satisfaction of knowing that it was burning in their wake. Within two days, however, the fires were extinguised, and Sundabar has since rebuilt from the attack.
