Blizzard North developed the sequel Diablo II (2000), and its expansion pack Lord of Destruction (2001). Following these releases, a number of key staff from Blizzard North departed for other opportunities, such as Bill Roper.[17] Vivendi made the decision in August 2005 to consolidate Blizzard North into Blizzard South, relocating staff to the main Blizzard offices in Irvine, and subsequently dropping the "Blizzard South" name.[17]
