Elder Scrolls Online
There were three guilds created shortly after launch named Stonewall Pact/Dominion/Covenant. They have since disbanded and some folks went over to the 'Order of the Black Crow' which is a LGBT friendly guild. Now that guild is mostly inactive, the bank has been emptied and some players from Stonewall that joined them have since left.
