Guilds and clans are private groups who band together, usually under a common cause and play games under their groups moniker. Sites in this category are about groups that are active in more than one Blizzard game, sometimes all of them.
This category contains links to Blizzard Entertainment game categories. Sites should be submitted to the proper category for that game. Sites about multiple Blizzard Games should be submitted to Fan Sites.
