War imprisoned within Iron Canopy

While War was on his way to kill the spider queen Silitha. He was captured by her Broodlings and brought to the Iron Canopy. The dungeon resembles a medical facility and has spiderwebs everywhere. Deep inside the dungeon you find the Abyssal Chain. With it, you can remove the armor from spider mini-bosses to beat them. After defeating four mid-sized mini-bosses and a huge spider with blue crystals on her back (Broodmother) the entrance to Silitha's lair would open.
