Rogue Hideout is a special military building that can be won during Events. Rogues can be trained with this building. Training a Rogue does not cost any coins or supplies, but will take 24 hours. The first two slots to train a Rogue are free.
Previously The Rogue Hideout could be bought at the Easter store during the 2013 Easter Event. Prior to the Easter store closing, one could buy this building for 400 Easter eggs and buy additional two more slots with eggs and diamonds, but now these slots can only be bought with diamonds.
